When will you finally add the option to turn double XP off? There are a lot of players who don't want to use it.

I've read dozens of threads regarding this problem, but no help was given whatsoever. I just started playing after a 1 year break and this issue has never been this annoying before. Every second combat I engage the camera will just go all over the place, when using the right mouse button. I never experienced this problem with any other games, even MMO's like WoW and Guild Wars never had this problem. It's really frustrating since it's the only thing that makes me want to quit the game again.
