The truth about kalista, lee sin, Zed, leblanc and the like
With the sheer amount of QQ threads about these champs one would assume they are op, but they aren't. I fear riot gets the wrong impression by all these threads. They see people complain, check all the stats, realizing these champs are not op, and then conclude the community to be braindead.
The truth is that these champs are not op (maybe a few of the hyper mobiles are a tad overtuned, but nothing to write home about). But that isn't the problem!
The issue is not that they have high win rates (they dont) or that they dominate games (they dont), the issue is that they are annoying as a venereal disease drip to play against
They don't need number nerfs, which would just lower their win rates while maintaining their frustrating gameplay. They need reworked abilities that fit into the game. Excuse me for saying this, and maybe it sounds ridiculous, but you cannot give one champion 4 flashes on a 2 second cd while some having no mobility except a 5 min summoner spell. You just can't do that and expect it to be fun to play against.
Yes, it can be balanced to make the champion not dominate games (most of them have sub 50% win rates) but that doesn't make it fun!
The truth is that these champs, and anyone else that comes along like them, will always be annoying, unfun, and cancerous, regardless if they are actually good.
