In content that doesn’t matter I will pull if the tank is doing 1 pack at a time. In TW in a lot of groups you can just straight up beeline to the boss and kill the trash before the boss, yet you still get tanks that do 1 pack of 2 mobs at a time.
I don’t force the megapull, but I’ll pull 2 groups together.
Granted, I’m healing this patch so I can judge how safe that will be more than if I were DPS.
