Casting regen before pull

[Zakalwe]

I notice a lot of people here saying 'healers' when you should be saying 'WHM's'. As a SCH I have never defends a tank before a pull and messed that pull up.

Can also be a Scholar's healing pet, though in that case it would be a regen left over from the previous fight, but if not removed it will still mess up the aggro on the next pull.
