You live in an illusion. It is like saying "policeman saw me.being assaulted and they came and saved me". Which means simply that when shot goes down they have to do something.
So stopwatch had to be nerfed and not because we said so but because it's unhealthy item that of all things ruined LCS so they had to act. Rengar rework was a failure and they knew it. Same like kog maw. It was so bad they had to revert it at some point.
Zoe nerfs great. Not like first they gave us ridiculous 0.25 sec nerf so she can be broken sand do glad"balanced" plays in LCS longer. Plus it doesn't fix anything since she will still be able to oneshot people with half an item. Zoe doesn't need nerfs like that. She needs damage nerfs. More precisely scaling nerfs.
They noticed lack of bruiser keystone in November. They were doing literally nothing being lazy and kept put it off. It will be 5 months. But of course they managed to create new tank rune in the meantime and reacted immediately on e.g. kogmaw with unnessecery buffs. 3 days kog wasn't top tier and got buffed in pbe for next patch. Biased as fk.
Mage itemization was a long topic already.
Let me remind things they never listen. Dynq. At some time they had to bring back soloq but intentionally didn't do it. Who cares about player experience of veteran players if casuals and baddies give us money and climb for free.
Jayce broken for 2 years. Nothing done. Gnar finally after 4 fking years some nerfs. Twitch strong entire year, nothing done except some band aid fix that does nothing actually. Tanks still overtuned with damage. Gp finally getting some nerfs but they don't change that much since his dumb playstyle that wins lane for him won't change. He will just Q you in lane 50 times instead of 55.and wiłl keep standing safely on the barrel. Btw do you remember ardent censer? They didn't nerf it with dumb excuses so LCS can have longer teamfights and shit. Up till now Lulu is broken, same Janna or healing supports. Denying a kill with one click to even a super fed assassins.
TLDR:just because they did something what community was talking about doesn't mean they listened. In these cases those fixes are a must and many of them don't accomplish shit or could be done long ago but they did t want to move their butts or simply wanted it that way.
