First of all, I didn't yell. Apparently you're blind and didn't read the first paragraph I made before the one you quoted since I said I asked her kindly to stop. I can regain aggro but if you prepull regen the tanks you will be getting hit before said tank can gain aggro. It's wise to let the tanks get aggro first BEFORE putting on regen. That should be basic knowledge for any healer. To still have to deal with that at lvl 70 is beyond bad and it's parties like that, that make tanking more complicated at least to me.
