Season 7 most needed balance changes
What is a Aatrox? I have never seen it. This champ has been left out in the cold for too long. Even though I have never played him I feel bad for his mains.
His combo is just too strong. You can't have a lv 2 Malphite ultimate on a champ with sustain and tankstats
Since his release just accept the fact he is a better bruiser than assassin and adjust him according to that instead of the other way around.
No I don't want to farm under my turret surrounded by 5 traps. Also the traps are almost a point and click stun. She feels a bit too oppressive right now.
Please the rework
Can we finally address his real problems (Barrels, ult range, bandit mastery) instead of making his early worse and worse while it won't affect his inevitable late game.
Nerf the slow on his ult
She has been freelo in soloQ for too long now. 3 years exactly with a winrate of 53%+
Whenever I get hit by her Q Leaverbuster tags me as afk. Also add more lane-interaction. Pressing W and walking away with shield is not what I had in mind of PvP
Needs another rework that is less frustrating too play against and fits more with her theme. Valor is not just a taxi.
100-0 by pressing R from outscreen range while applying a slow and hitting multiple targets doesn't need the insane true damage. At this moment he is overtuned.
Remove this champ from the game
Does this item really need 45% bonus armor penetration?
Busted item. Remove it please.
Each time i bought it during season 6, even during the tripple adc meta, it was a complete disappointment. Either rework/buff the item or remove it since it is a noobtrap.
Just keep in mind that the same people who are complaining about this item are the same people who will complain about mobility creep later on.
Melee only like it should have been on release and everyone foreseen the problems.
Remove the lifesteal. It is already an abundant stat in the game. Bring it more in line with 
Permahealers have proven to be unfun and toxic.
Revert the Q buff.
Revert the rework
I left out the obvious ones that Riot already said they would address.
