Is this a thing now??

Oh man, back in the early days when I was a new healer, I got my ass chewed out for using regen before a pull and mid pull. Now I either use a shield before a pull (used to be Stoneskin when I played WHM but that is no longer) if I'm using nocturnal or I'm playing as SCH (alt) or I just wait until the pull is done and use big heal + regen + benefic if necessary. Basically whatever is necessary to keep tank alive.

If the tank is literally getting too close to dead for my comfort, I pop the CD heal or swift-cast or surecast benefic II (whatever I have available).

Parroting what some others said, but healers should not be using regens right before a pull or mid-pull for sure... I've had similar issues (and the exact opposite: NOT getting healed) when I've played as tank and was given similar uppity remarks. It's like... "Please take a slice of humble pie, because you're making my job and YOUR job unnecessarily harder." then again, healing has been boring lately. Maybe this is healers' way living on the edge for a bit of excitement. (Just kidding, this was going on long before 5.0.)
