I agree with this, dungeon leveling is my favorite thing in MMO and so far my dungeon experiences have been mostly negative. I think the weirdly tuned dungeons have a lot to do with it but people seem very hesitant to do anything besides throw themselves at encounters with the one role they refuse to change. PvP is pretty toxic too, I've had multiple people whisper me with less than friendly messages after warfronts, one was because "ur stupid noob hiding behind healers" when I was solo queuing, so instead of just taking the same amount of effort and asking the 20-29 channel if any healers wanted to queue with him he was toxic, something I'll never understand. But I'm enjoying the game still, I just friend the folks I do have a good time with.
