99% no, but I guess you can't know unless you've tried.
Also, I think it's a cause, as WoTLabs was created by NA players and initially populated by mostly NA players.
I usually pick an avatar because I like the image, but I guess a big part of it is what's been mentioned many times in this thread; connecting with a fanbase.
Still, it's usually just me seeing something and thinking "That would be a great avatar."
I don't, I just play osu and minecraft now.
I was doing better than I ever was before, then I just didn't feel like playing. I just stopped having fun, I guess.
