Now that I am back on a summer raiding schedule, I am finding that I have to disable nUI+ on both my warlock and hunter. The performance is really bad and costs me almost 900dps on the warlock and 2200dps on the hunter. I may have to do the same with the multi-boxing my RaF toons, which really hurts. Hopefully these issues will not be there in 6. I will continue playing with the setups and testing to see if I can isolate the lag perps.
