first off all...
no champ has more than 4 skills. and i dont mean nidalee jayce etc.
i mean ppl like kai'sa, a champ who has so much textbox in her skills that she could be 2 and a a half champs.
next get rid of silence.
theres a reason almost no champ has a silence.
after that fix hitboxes/the map.
if you stand at certain parts of the map or in certain angles, a cait can aa an ashe on MAX RANGE (650) and yet ashe can autoattack back without getting closer (her aa range is 600)
after that... mordekaiser. enough said. remove this 200+ bug piece of shit or rework him.
next do something about crit. its the worst feeling when you have a 70% crit chance and the enemy has 30%
and you dont crit him 1 time in 10 aa's but he crits you like 6 times in 10 aa's.
all champs should do well if you play them with skill not with luck.
next tanks. give them more armor and mr and hp, but less dmg.
it cant be that an adc who is 7/0 loses the 1v1 with a full tank renekton that stands 0/13.
thats insane.
fix the remake option.
its a total mess. it tells you that you can remake because 1 or more player lost connection to the game.
what a fucking bullshit.
if you move from 0:00 to 1:30, but then you dont move from 1:31 up to 3:00, the remake option still appears. even if you were connected the entire game.
i think if you focus on that first, the game is heavily balanced alrdy.
