May I AST you a few questions?

I only played WHM, but have an answer for question 1:

First the tank should have enough life to survive the buster. Then you time your heal accordingly to the damage. This means when you see the cast for a tankbuster, you start casting a heal around 2 seconds (depending on your cast time) before the tank recieves damage, so that your heal hits the tank right after he got hit by the buster. So he doesn't sit too long at low HP and get killed by some auto attacks while you are casting.

I think this called pre-casting a heal o.ô; Needs a bit training to get used to the timings.
