These are and have been the only (about 98% of the time) thing to kill my WW barb (MP7). I have tried a few different things but nothing has worked. While the occasional thread does pop up to validate the problem, no one has yet to come up with a solution.
Please note that I am not bitching. I do not have the knowledge to fix it. I am waiting patiently on someone who does. Until then, I just set my death handling to 'logout' so that the bot just leaves game then starts a new one. I'm still able to maintain roughly 1k-1.1k IPH. Not great, but decent....
