Do ret pallys do 100k dps?
So I have a near bis pvp spriest, and a bis sm pvp ret so I have an idea of the kind of damage ret has. Can someone explain to me, how a ret paladin kills my near bis shadowpriest from 100-0 in 3 globals while I'm in dispersion repeatedly? Just to be clear, I have all priest buffs up on my character including inner fire. This guy just drops off his mount, stuns me, I disperse, and I die 3 globals later from 100-0 during dispersion. He did this repeatedly. Dispersion is -90% all damage for the duration of the spell. Which means, he has to be doing well over 250k damage in about 3 seconds considering I have resilience/dispersion/shadow form/my bubble up. Probably more like 300k+ damage, meaning over 100k dps. One of the times I trinket his stun, and fear/disarmed him, then dispersed. He killed me in the same 3 globals, during dispersion, while he should have been disarmed?
Now like I said, I have a sm ret pally and I do not 2 shot shadow priests in full gear even outside of dispersion. So how is this guy killing me over and over with dispersion up from 100-0? What am I missing here? Is the dispersion tooltip wrong? What is not working properly?
