Oh, I'm sorry, where did those stats come from? didn't see what group that study was done on?
And as for the 2nd picture, guess that's the difference between wow and gw2, you can mash buttons without any GUI and still win in gw2 but seems like you need to actually try in WoW.. hmmmm.. seems like the weaker minded people would play by mashing buttons....
*troll mode done*
In all 100% seriousness I have actually been thinking about going to GW2 because it looks epic. We will see how it turns out after a week of live servers.
