For me it really depends on what role I am in. And I am trying to "master" at least 3 champs per role so I can be versatile in ranked while letting others hopefully get their preferred/best roles.
Top is my least favorite role, but if thats where I end up I prefer
or
. I prefer these simply because I like to have a ranged poke, because my biggest weakness is melee farming next to enemy champs lol.
ADC is my next least favorite. But my two champs are
or
I love Jinx' kit (and I honestly adore her laugh lol) and Varus has a nice poke and a fantastic ult.
Jungle is my third role of choice.
or
or
Seems like a lot of people dont like GP jung, but I like it, self buffing, healing, and a low cd Q. Plus being able to utility ult/gank (granted you dont need to jung for that). Sion is just plain fun lol. And So is Amumu, his kit is amazing for quick clears and ganks.
Mid and Supp are tied.
is excellent for both, but otherwise for Mid
or
Syndra can be tricky against mobile champs, but otherwise she is really fun. Annie is just fun being able to pull that random stun out.
For Supp, the role I mained for a majority of my time on LoL...
or
Thresh is obvious, hook and lantern, decent ult. Blitz is just plain fun lol. And short Ult. I just wish they would make his ult passive able to toggle so you dont aggro minions in the jungle using
I even take
supp sometimes. Great kit for that. Powerful Q poke, W slow. E Stun. And a great ult for picking off those guys the just barely make it to their turrets lol.
Other champs I like but don't pick too often unless our team comp calls for something like them.
Forgive me, but I'm gonna do some shameless self promo on some of my League vids lol
