Mainly Lux's hit box and Riven's 'R', but many other complaints too.

(Lux) Basically, I was taking significant damage and couldn't see why; also I was outside of Lux's visual aoe (not the ult) by two jinx character widths and still got hit by the ability. (Riven) Riven's ult never activated the first try and I always had to hit the key 3 times before it would activate; by then I was killed before I could do anything (it could be lag but it only happened on 'r'). Apart from that, Talon's damage scaling seems to be off (way too strong). Everyone bans Illaoi in normal draft. Yi is a jg monster again. Karma's mid game seems a little too strong. Morgana might need tormented soil looked at (third level tormented soil kills all back minions). Kench is nearly invincible early game. There are too many slightly and very broken champs for draft bans to really matter at times. These last few updates seem to have affected the game negatively balance-wise.

Now I may have lost a lot of these games, some of them my fault, most of them another lane had collapsed; however I want to add all these champs were winning 1v4 matchups, dealing 1/4 - 3/4 health worth of damage at level 3-4, and other such obvious things.
