I love it when Riot nerfs/reworks champions to the point where they're better off as supports.
The most recent champion this happened to, was
, where he got 10-15 base damage off his Q level 1 (Can't really remember which one it was, but it was an absolute shit ton) which made not only trading frustrating, but also CSing. Other examples would be
, taken that Brand got a buff which might bring him more viable in the mid lane, and Malz last season where picking him mid was just an all around mistake. You could also argue that
had this type of treatment a few seasons back, but he was put in the support role frequently as well. Seriously don't get why it's so hard to not over-buff and overnerf champions, if you see their winrate/playrate drop by more than 5%, then you know there's clearly an issue.
