And that is outright false considering the amount of non raiding content there is to do in WoW at endgame.
PvP, Dungeons, Pet Battles, Achievement Hunting, World Quests, Roleplaying (doesn't even have to be endgame), World events, Micro Holidays and god knows what else.
I get you like GW2 a lot but to claim WoW solely focuses it's endgame on raiding alone is disingenuous and close to dumping on one game to make another appear better.
And what else do you have in the "PvE environment" besides the Living Story and Events? The Living Story is basically the same as how WoW provides it's story content with patches (Broken Shore being debatable with how awful it was) and as for events it has invasions, micro events and holidays.
