Generalists got nerfed into Specialists causing balance issues
Because more generalists like Jarvan and Lee pop up and take their place
Riot needs to nerf multiple champs at once instead of one at a time if they want real balancing progress. The prospect of a fighter rework isn't at all as hard as they made it out to be.
Nerf Kha and Elise and Eve get Jarvan and Lee
Nerf Jarvan and Lee get Voli and Xin and Vi
Nerf Voli xin and vi and you get nocturne pantheon
Etc
**Riot needs to look at all bruisers and make proactive choices and decisions as to what they can and cannot do. Balance cycles aka buff and nerf will always happen but pro activity fixes this scale of problems **
