I remember a time
When Ziggs was one of the most hotly contested pro picks, and was considered outright OP... because his waveclear was too good. That's it. He could stall out matches by clearing mid with one Q and then clearing bot with his R. He got nerfed multiple times for it. The nerfs were simple number tweaks. Less scaling on Q, longer CD on R. They worked. He's been balanced ever since. It was a manageable problem that was easy to address.
Now Champions are OP because they can spend 90% of the match untargetable, or they play like a bruiser and an assassin at the same time and can use every ult in the game, or because their ult can undeniably execute you from 50% of your max hp in an aoe, while resetting and generating double kill gold. And most of these are inherent to the Champion kits and literally cannot be fixed unless brand new Champions get hit with mini-reworks or ability updates. Amazingly enough, some of them have gotten their abilities updated shortly after release (
) and yet still cause problems because their core design just lets them do too much. The fact that updating a Champion's abilities 2 months after they come out is starting to become standard should be a massive red flag for Riot that they need to stop letting designs like this go live. Take us back to the days where "too much waveclear" was the standard for being overpowered, not "earning the most gold in the match by a margin of 7k on a support."
