I have to say this, and I hope I don't step on any feet as this is my first reply/post ;D
I have to agree it is annoying as muffins when someone kills u but I get over it but it seems people need to roll around it groups cause they are week and can't attack in singles, it's annoying that I have to roll around with someone to be safe, but as I said I dont care, what gets to me is people that stop others completing missions by staying there and slaying the boss u need, then threatening to make u wanna reset, They know who they are, plus it's funny when ur own side is against u, hello I'm not the ememy lol.
So please attack me in groups when I'm alone, but don't be rude threaten and make missions hard u know u would not like it.
