If it's speedrun pulling you're having trouble with, the quality of the tank can make your life incredibly easy or difficult.
Any buff on someone adds enmity against you, but if the tank is able to get enmity on every mob on their way to a stop point, that gives you freedom to cast Eye for an Eye or Swift-SS during the pull.
If the tank has enmity on every mob--or even all but a couple--then you're also free to Divine Seal and Regen, using the cooldown after to move near enough the tank that they can Flash off what couple mobs might have turned to you. Seal will be up, you'll be helped, Cure II is ready to spam.
If you still have Swiftcast available at the time DS is gone, I find it useful to Swift-Holy in the center (or safest near-center spot) of the group, again using the cooldown after to reposition. Four seconds of stun on every mob is enough time to do a Stoneskin cast, maybe activate a cooldown (PoM, SoS, or DS if it's up), and still be casting a Cure II.
