Riddle Me This: "Regen on pulls is bad"

[tinythinker]

If you cast regen on the tank -as- he is rushing towards the mobs, you will pull hate and the tank will need to work overtime to prevent the mobs from rushing after you first.

Better to let the tank build up hate first, then cast Regen before going into Cleric Stance. ^^

The reason not to use regen before a pull is because you will be the top target the moment the tank goes in to attack. Once the tank has aggro, feel free to pop a regen on them but before hand is dangerous for you and can mess the tank up, especially if they can't manually remove it easily like on PS3/4

OK, so I had it right EXCEPT wait for Regen until the tank finished pulling first, and lay off of it if s/he needs to reacquire aggro. Thanks so much. Lots for me to learn. I hope maybe other new healers will learn from my error.
