I know it's been said before, but if you don't want to see the WoW vs. GW2 fight, turn off general chat and don't read the comments on youtube.
The fight is there, and it'll probably be there for quite a while, but that doesn't mean you can't seperate yourself from it.
The thing I'm trying to say is, don't let other people ruin your experience.
If that means you have to isolate yourself from them, so be it.
