I have yet to see a GW2 GAF player that plays regularly, go into ESO or WildStar threads and shit in them, like I see very specific WoW players here on GAF go into every, single, GW2 thread and shit on GW2 even though they claim they stopped playing ages ago.
There is a difference between defending what you like, and making it a point to go out and attack what you don't. I like GW2, so naturally I'd defend it - but I'd defend WoW as well because, even though I'm retired from it, I still like it. I would defend the good points of ESO, and the good points of WildStar, but I wouldn't go into either thread and talk down about it. And yet, that's exactly what some people do here on GAF - they see a thread about a game they don't like, and it doesn't matter what the thread is about, they'll go in and talk at length about how much they don't like it. That is what boggles my mind.
I'm at the point now with GW2 where I'm not so insecure about the game that I'd need to bash other games or blindly defend GW2, but it does ruffle my feathers when people go into GW2 threads and spread blatant and bald-faced misinformation. That's all.
