Predator is BROKEN and needs a fix asap
Since Predator was first introduced in November, I've had insane lags and FPS drops every time there's someone with this rune in a game. Either an ally or an enemy, it doesn't change shit, when I cast certain spells my screen just freezes for 1-2 seconds and makes it impossible to play.
I think that predator is a big part of the FPS issues that have affected a lot of players lately, and I hope Riot will give a look because those FPS drops ONLY HAPPEN when there's someone with that rune. This could potentially lose you a game (and I was close to losing one because of it).
Fix it or disable it until you do. Right now I'd rather ban a rune than a champion.
