The way I like to look at it, is the noobs will always die. If you died in the group, your a noob. Plain and simple. Everyone's death can be prevented if everyone does their job. But if one ***** is pulled out of the assembly the whole thing collapses. So in short, one guy screws up and everybody pays the price.
I don't find it funny if the rest of group dies, however I can't help but sit and think how much it's their fault. I realize that as a tank its my job to prevent deaths from occuring, and often I do.
However, if I tell everyone to run like hell and they sit there trying to take care of the mobs while I'm doing exactly what I told them to do, when they die its their own damn fault. I do things in a way that can normally save others. I'll taunt a few times, hit sprint or dash, and run.
I've not only pulled the mobs GOOD, but I'm running fast enough that I save my *** as well. But if the group decides to pull aggro, then for all I care they can die. Just my 2 bits =)
