[GAMEPLAY] Mordekaiser making FPS drop like crazy mid/late game.

Ok look, I'm far from having a top tier computer, but know that I've **always **runned League at max setting and have never experienced any lag whatsoever under normal circumstances (the server being OK and my ISP not being a bitch). But with Mordekaiser around in a game, I'm always getting huge FPS drops when the teams start to group, more specifically in the mid/late game. It's only whenever he appears on the screen, because as soon as he dies or walks away everything gets smooth again. It also happens if I play him, which makes it impossible to teamfight as the game progress. When I'm playing him, I only experience this problem during teamfights, again. I've tried to lower all the possible settings to low and, appart from the game being freaking ugly, nothing changed.

I've done some quick research and I found many people complaining about this situation aswell, which gives me the hint that it must be an optimisation problem about Mordekaiser. I don't know what that is, but please, Riot, make it stop! Right now Morde might be banned 95% of the time, but as the meta change and as the players realise how to play against him, he's going to be less and less banned and this means I'll have more and more bad games due to FPS drop. Don't do it because of my specific request; do it for all of those who experience the same problem, because I'm far from being alone.

I don't remember ever posting on any boards of LoL, so please consider this as a desesperate call for help. Happy semi-finals everyone, Mathieu
