Tanks, please use buffs

[Cenerae]

Please do NOT forget that Living Dead/Hallowed Ground/Holmgang are also cooldowns!
This is particularly important for PLD, though: for absolute maximum effectiveness make sure you pop HG along with literally every other CD you have available at the moment, just for EXTRA safety!

You should have approximately zero cooldowns ready for the next pull - oh, wait, you do have one! SPRINT! That counts, right?

I see a couple of DRKs pop Living Dead at random while at full hp mid fight. I assume it is to assert dominance over the enemies.
