I can't decide! I have a favourite champ I like to play a lot, but then it gets to the point where I feel like i'm not playing with a point, and I start playing champions I don't already have mastery 7 on. I know playing should be its own reward, but I tend to be a be of a completionist in games

I like to diversify my champ pool on all roles. Here's my list of champs for each role:
ADC = 
Top = 
Mid = 
Supp = 
Jungle = 
Its always a refreshing experience to hop from one champ to the other on each role. Keeps the game interesting and alive for me atleast.
EDIT:** People seem to be triggered by my champion selection due to them being females, LOL. Chill, its just MY preference in play style. I don't see why does it matter if I play male champions or not ( of course I do, just none of them suits my style competitively )**
I dislike League of Legends, outside of Zilean 
and Yuumi 
...
Maybe Pyke 
also? But he is too OP, I dislike to play him.
Honestly, they both get Picked or Banned, and Im like "Eehhmmm...".
I tend to binge champs a lot, but can never stay on one
For me, lots. I used to "main" champions for a couple seasons at a time, but after my mains were each reworked, I stopped getting attached to a specific champion and have broadened to play a large pool. It was kind of painful losing mains to reworks, but I have found variety keeps things fresh as a veteran player so I don't mind anymore.

Present 
I have 11 champs at M7 and 546 total mastery score........ so I like a lot of champs, mainly supports
Lots of champs!!! I have made a champ pool and have 4 champs for each role:
Top: 
Jungle: 
Mid: 
ADC: 
Support: 
Currently trying to get all of these to mastery lvl 7 (got 3/20)
Yes, I will main all of these, it's a wide pool but I will never be banned out and I can have a variety of champs to choose from to counter enemy champs.
I only play Lux
Lots of champs that have super low pickrates.
I One-Trick in Ranked.
And I never play my Ranked main in Normals.
In Ranked, the "point to play with" is the win at the end. I don't need any other point, so I'm fine just playing my main. Reciprocally, if I do NOT play my main, I'm not doing my best to win.
And in Normals, the win isn't important, so I do need another point. Usually it's farming chests, or mastery token, or just trying to learn some new champ. That pushes me to play other champs.
i came to LoL from Dota2 cause one-tricking felt easier and much more rewarding in LoL,than it was in Dota so i'll vote for one-tricking

Trying to learn
yo bro play like 5 different champs and master them so you can have some variety but dont do A LOT of champs then you never really master a select few champs to there full potential so if i were u i'd add a third option to the poll saying a select few champs, also dont do one champ because then it gets repetitive and boring
I play a specific group of champions :v
i tend to play so many champs but then i have tried one tricking for a bit because it would be so good to say im the best of thie champ in this region or world ... I feel like thats the ultimate goal with oen tricking but i just lose the willpower ;-; amongst my friends im the guy who can do anything though XD not to perfection but to a good state :S Ive been told they dont know how im gonna play out which tbh i like cos even idk how i play out
so playing different champs and being al lottery player of whats gonna be my outcome feels good XD

ADC :
Supp : Dodge or some time
It depends on what you play, if you play ranked, you're probably a one-trick pony for the efficient climbing, but if you are a "For Fun" player, multiple champions would be more fun for you.
Since I play ranked, I keep my pool small: 
I want to be able to play the few champs I like instead of having them get beaten by the nerf bat repeatedly if they show up in another lane or in pro play.
I play aram mostly so I can play everyone, but when it comes to norms/ranked I pretty much only play 
I'm in the middle tbh. "A Select Few" would be a better answer for me.
Morgana , Irelia , Neeko , Nam i, Zoe , Leblanc , Syndra , Akali , Jinx , and Xayah are my squad (Fiora , Camille , Kai'Sa and Rakan get honorable Mentions :P) As you can see, I was very happy when IG won worlds cuz I got a skin for all of my favs LOL [sg-miss-fortune]
I play one champ for a long period of time until I feel like I've mastered it and then I switch to another champion and try to master that one. I'm always looking for the next off-meta pick to make work.
I like to play others in ARAM or vs bots or when my champ is banned and I can´t or dont want to dodge.
But obviously I stick to one champ in rift. If you would ask "why" it would be hard for me to answer.
give me 
since 86% of my games have been on her this season. I just like playing her as it feels natural for me since her play-style is exactly how I play almost every other game. Long range kite you out rain damage from a big distance away.
I prefer a large pool of champions, but I can play one for a while too.

and I used to main 
but he kinda not good at all rn in the supp role so
It just depends on how much time you have to play. If you're limited to a couple games a day like most people, I'd try to master one. If you play all day long, you're definitely going to want to branch out a bit.
Both can be fun, Personally I enjoy sticking to a role religiously and just bringing in any champion you can into it.
That's how I ended up playing Illoai support during the tank meta and Zed support when enchanters got nerfed.
As an ARAM OTP...
Supports, ADCs and mages mainly. In that order.
There used to be more, but then reworks happened. Used to enjoy bruisers way more than I do now.
Used to enjoy ARAM more to, but then 
happened. Damn thing should have stayed in Poro King, with the other old items still available instead. And no map-specific balancing.
Got about 3 champions I know on that "other map", with another 3 or so I can play as "backup"-champions there.
I have a handful of champs i enjoy in every role except maybe Jungle.
Nothing makes Jungle fun. Nothing. Fuck that role.
I used to like to stick to one champion, but once I decided climbing wasn't fun anymore I started branching out. Up to season 6 I played almost exclusively, then when she was bugged I switched to , after he became pick/ban I switched to . The following season was when I started playing more champions. Including 
. Last season I barely played, but I really enjoyed .
This season I have barely played again, but have had a lot of fun with off meta on a lower mmr account (can't call it a smurf anymore if the actual rating is higher than my main lol). There I have played mid. Side note, Rakan mid is actually disgusting if you can make it to protobelt.
I like playing a verity of different champions because if I play one champion to much I end up just getting bored
i like playing tons of champions but in fact i'm better playing one champion... and i want to climb! :(
one-trick-ish.
I have about 10 champions that I play. I've bought brand new champions right on release and never played them (Yuumi and Pyke for example).
I guess I'm just picky.
I personally like having several champions under my belt. It make you more versatile and when you are stuck filling you don't waste anyone (and your's) time by quitting if your ONE champion get ban. I think League is about trying different things and well in this case champions.
Always feel nice to fill a spot no one is good at and be able to pull your weight, but I think you should probably stick to a select few especially if you have irl stuff in the way. Can't be good at anything but I prefer a jack-of-all-trade to a one trick pony.

I used to play a lot of , (have nearly 1 million points) , then you realize that once you get out of silver, it's basically the most useless thing you can play in top lane. Sure when team fights go around you pretty much auto win, but in the laning phase, you almost always lose. So I stopped playing him because it's like, if you don't cheese the ever living f out of your laner at level 1, you won't win the game unless the game goes well over 30 minutes.
Personally, I like playing lots of different champs and different builds but I also like having that comfort champion that I can always play and feel like i'm having a good time tbh
I'm a Juggernaut lover and dyed-in-the-wool Toplane main.
In no particular order: and the occasional 
.
I was trying to pick up at one point, but just wasn't able to get into it. No offense to Aatrox players intended.
In the occasional Jungle: . Used to play 
there too, and may pick him up again come his VGU, but only time will tell on that one.
As you can see, I play (Or have at least played at one time) about 12 of the existing Juggernauts. So why don't I grab and finish the whole set, right? It's probably because I don't play her, but I have this notion that her Rune viability is extremely limited. This may be due to the fact that nearly all the 's I've seen use Klepto. No offense to Illaoi players intended; if I'm wrong, feel free to correct me.
the point of playing this game to me is having fun. so u play what u have fun with. whether its 1 or 2 champs to 50. i only play a few as thats what i enjoy. but i havent played in awhile , thats another story.
