I just cant seem to find the champ that fits me. Below I will list somethings I am kinda looking for in a champ, if you know of anyone that matches them please let me know in the comments so I can try them out!
Requirements:
Sachabot1 votesRenekton is the closest that comes to mind for me.
3ofGot40ve1 votesHe can only play top cant he? Also does he have sustain?
Sachabot1 votesThat's why I said "closest." He does have a heal built in.
Sachabot1 votesGraves would be a second close choice. Maybe Quinn? Cho'gath? You're asking for an awful lot, I'm just trying to get close as possible.
Sachabot1 votesAkali? Diana?
3ofGot40ve1 votesI use to play akali pre-nerfs, is she even viable anymore?
Brimaz The King1 votesany top laners can buy 
Sachabot1 votesShen?
Vexful1 votes
3ofGot40ve1 votesI heard he is kinda hard to play. Also does he have any sustain?
Vexful1 votesQ: ranged poke, adds 1 stack of your passive per hit, hits harder on way back to you. Not hard to use. W: throws a dome. The dome gives you a shield that scales on AP and stuns anyone in there if you are also in there. E: a roll that is your mobility. If someone is near you after, click to AA them and you teleport to them. R: Your sustain. Also your nuke. Also you're "I effed up" card.
Meets your sustain requirement, can mid and jungle, mana isn't really an issue on him. I mean hell, 1/3 your best items give mana or mana regen anyway. E, R, and passive have mobility.
Just watch where your clone is to ult and even if you dont land the stun dome, walk in it for a free shield.
Brimaz The King1 votesGnar, Sion, Garen, Irelia, Jax, Volibear, chogath, Malphite, Nautilus. Tell me what you think of any of those. Because they are in that wheel house of what you asked for. Also any champ with mana you can't spam abilities. Only In trades or Siege cannon csing. Edit: what's your playstyle? How do you normally like to play your videogames? Aggressive, Passive, Supportive, Damage, Tanking?
3ofGot40ve1 votesGnar: I own him. He is pretty fun but I honestly suck at csing with him(that can be fixed though). Also he doesn't have sustain and can only play top right?
Sion: Whenever I play him I seem to always be out of mana. Maybe its just me.
Garen: I enjoy garen, he actually fits all my requirments except the 2 roles part. High ban rate, not as bad as jax though.
Irelia: Played her once, didn't really enjoy her.
Jax: Perma-banned
Voli: Fits most my requirments. Haven't really played him though
Cho: Fits all my requirments except mobility. but even then his base move speed is one of the highest
Malphite: I have trouble with his mana, kinda same deal as sion. don't really enjoy laning phase with him.
Nautilus: Never tried
Brimaz The King1 votesI can't believe I forgot Darius GOOD CALL. Also Nautilus is lots of fun bc he's like a thresh/tank dude. Need more than one person to take him down. (of course unless you get poked to low health) But then you can hook away to any terrain. Also the mana Problems you have....don't use mana for csing also freezing lanes help a lot. It does mean that most times you'll be under your tower but then that means your enemy can't cs. just watch out for tower dives from a jungler.
3ofGot40ve1 votesWhat about darius? hes pretty easy right?
Tohob1 votesi'd have a ton of reccomendations if you dropped the mana thing. if you have mana problems, i would highly suggest 
. a surprising number of champions with "mana problems" are cured quite easily with a simple 
, which is a great item even without the mana.
that said, 
meets all the criteria, being manaless and able to top or mid within the meta, or jungle slightly outside of it. apart from that i haven't seen her banned in years, she's crazy mobile with her ultimate, her mechanics are very straightforward, and sustain is her middle name. (her last name is "for days".) 
is also extremely similar to akali, sacrificing sustain and energy for some range and damage, but they're both good.
is one of those champions that has all his mana problems cured by a , which is the core item on him. he can ADC and mid, has a great distance blink on his E, and tends to build lifesteal, so sustain isn't an issue. he does require the ability to land skillshots, so depending on how mechanically easy you are looking for, he might not be EZ enough (get it?)
is another top/mid energy-using champion, is very speedy with his E, and i believe is still useable with 
for sustain. E-W combo is good for waveclear, although he can be somewhat mechanically challenging, though if you're comfortable with ult + 
combos, you'll do just fine.
fits all the criteria almost perfectly. he can top and jungle quite well, doesn't use mana, has crazy mobility with his E, sustains and waveclears at the same time with his Q, and is about as mechanically challenging as blowing up a balloon.
a couple of honorable mentions include 
. most of these champions fall victim to the "multiple roles" requirements, though some are just here because i don't play them and therefore don't have anything to say about them.
3ofGot40ve1 voteswhat would your recommendations be if I dropped the mana thing?
GrabMaster1 votesOk so Vlad can go top or mid. Just try not to play against say anyone like wukong or j4. Play safe early but still use q on them whenever you can. He uses no mana. Can go top or mid. Rarely will ever receive a ban. His w can get him out of bad situations. The only thing you should know is you will have to keep your e up to four stacks as long as you can. Do not do that early if they are playing very agro. Awesome sustain with cdr and will of the ancients. has great waveclear especially with cdr. Play like a baby with vlad and do not be afraid to give up a little cs early. Any questions let me know.
XIII Vanitas1 votes
DaStruggIeEzreaI1 votesKayle. Covers mid, top, jungle. Never banned. Heal provides mobility for roaming. Not mechanically challenging but getting ult timers right feels rewarding. Heal has some sustain. E wave clear easy. Bonus: Multiple build paths. Only con, uses a fair bit of mana if you spam heal.
Chespin20131 votesTry Vlad
no health sustain issues since you practically have infiinte of it. Can be player mid or top. Really easy to play and great waveclear later on. He doesn't really have any mobility other then his pool which gives him a slight speed boost but other than that he is a really fun champion and very safe. Do you want to be annoying %%%%? Do you want to do bullshit amounts of damage while having infinite sustain? Do you want to role play as a Vampire? Well worry not because Vladimir is the perfect champion for YOUUUUUUUUUUUU. Seriously he is one of the easiest and safest champions to play in the game, I highly recommend playing him, but one thing you must remember is learn how to LAST HIT. His autos might be a little slow but later on you will get used to it and also he can use his spells CS so that makes it even easier.
