I got harassment from a freaking world quest the other day. There was a non-elite, blue Wardens WQ with some random Satyr as a target. There were a shitload of people in the area so it had a lot of health. I was apparently the only tank so I obviously had aggro when he started evade bugging (I didn't move an inch from his spawn point). He kept bouncing back to his original spot when death gripped and it took me 3-4 tries to find a spot that he liked enough to stop evading.
In that time I was BOMBARDED with tells and /say shitflinging, people calling me a troll/etc and claiming I was being reported. Because a mob was evading out of my control, wasting about 1-2 minutes of their time. A mob that I was able to fix.
But yeah I understand that pugging everything is apparently the new normal in this game. I just can't do that. The only reason I'm even playing is because running stuff with friends is fun. In WoD I lasted exactly as long as my guild held together and not a day later.
Being able to actually progress in 5 man content while playing with a solid group of people I like is something I wish this game had years ago. I'm not saying I would have never quit at all but I definitely would have stuck around in Cataclysm for example. I stopped playing that expac as soon as the raid came out but I loved its heroic dungeons.
