Tanks and super pulls

[Wintersandman]

D) This healer realistically doesnt know what the hps checks will actually be like, so it's not a good idea to have them make the call. In addition, this healer is likely able to spam cure II at a minimum / can be easily mentored into an acceptable level of hps.

Or the healer is just flat out under geared for the content and thus can't keep the tank up. Cure II spam only goes so far. So does mana, if the healer can barely keep up the tank with Cure II spam and burn through their mana the super pull was pointless as you will be waiting for mana to refresh in between pulls.
