OK so I can't edit posts on mobile app WTF!

If you have to decide on a threat ability or damage ability go with threat always...unless you're way out in front on the threat meter and even then only warriors can effectively do any amount of damage.

Tanks set the pace of the dungeon run, if you're tentative on pulls or "too slow" the party picks up on it like a pack of rabid dogs and might start in with the bad tank talk. It helps if you already know the content from another job. Like in AK where you had so many deaths at the last boss, he probably didn't know where to tank the dragon, there is one spot you can stand and not take damage from the imminent catastrophe and he probably wasn't in it lol

Some groups like a vocal leader tank and others don't care either way, I just feel out the group after a couple pulls. If someone is confused or just generally derping around it's ok to say something or offer help, never be rude or nasty though :3
