Reworks
I don't think almost anyone likes reworks and there have only been a few successful ones for some people, but even if you think a rework was successful it might not have been to someone else and now their favorite champion is ruined.
for an example i really loved playing old warwick when i didn't feel like playing shaco because the champion was easy,strong and most importantly fun. even if it didn't take much skill to play him ok he was still a blast to play and wasn't that broken.
i so far haven't liked any of the reworks that riot has done because they always seem to kill a part of a champion and then i imagine me playing that champion for years and mastering it and suddenly all the time i have sunk into learning the champion is gone. a good example is aatrox. compleatly different kit with a lot of changes to skill cap and playstyle.
maybe instead of doing reworks they could make them a sepearte champion for a while to see what the mains say about him and listen to community and after a few months the changes could happen but only if the % of people who like the new rework is over 70%. i just read a Aatrox main community post that made me sad/cry because it was touching and sad seeing all those players lose their love for the game because riot wanted change. in this case change wasn't good. (Edit. link to aatrox main post https://boards.na.leagueoflegends.com/en/c/gameplay-balance/3mLooeYA-aatrox-mains-community-post )
so please. Stop reworking champions just for the sake of change
