Granted, the nerf to KJ's health makes it much shorter, it also makes the fight more hectic between phases, adds and such. If you don't have dispersion, you're severely limited to the amount of mana you can gain back (not counting the dragon buff, seeing as this is a discussion about priests in general). Throwing a shadowfiend out there for 3 minutes while going through your all out spell priority and popping one mana potion will leave you out of mana before you can use your shadowfiend again, in the long run. We run out of mana insanely quick, even with replenishment.
So it's either stand around and wand shit, or pop dispersion in between shadowfiends then return to your spell priority, which ultimately will be a dps increase.
