I've finally gotten around to leveling my tanks(all of them at once, actually, so far I think I like PLD the most, though DRK is fun to), and normally I end up OT'ing when one of the other tanks steps up to the plate to tank immediately. A few days ago though I actually got to be the MT in a Void Ark run and pretty quickly I noticed there were a couple things I'd need to come here and ask about.
Mostly this part. When I got to the bosses, I mostly just stayed in Shield Oath the whole time and mostly kept on using Rage of Halone. I know I'm not supposed to do that because I've got Goring Blade, Royal Authority, and other nifty toys now to boost my dps, but there was one thing keeping me from playing right. I can't see anyone's hate level outside of my party, so I was worried about someone from a different party or one of the other tanks catching up to me the whole time. About how much hate, roughly, am I supposed to make before it's okay to "safely" stop generating hate and switch to doing damage? Some rule of the thumb, perhaps?
That and, on trash, how much AoE threat is enough to put down before you do anything else? There were multiple instances where I'd flash two or three times, then the mobs lived long enough that if I started trying to dps I'd lose them. Normally in the 4 mans for AoE I'd drop two Flashes, then tap each of the monsters with individual bits of the RoH combo to maintain hate and that gets the job done, just sometimes that isn't enough in a raid setting.
So I guess to sum it up, hate. How much hate is enough to stop making more of it?
As an aside, main tanking 24 mans is intimidating, heh. I'm definitely used to the 4 mans by this point, 8 mans aren't bad either, but being the leader of that Void Ark was a lot of "Don't screw this up, just keep hate so other people don't die and stand in the right spot", heh. That'll get better with time I suspect.
