My highest level is PLD37 and I too came over here to see "what not to do" as the tank role - because being a Paladin, is y'know, a calling, a vocation...
I'm a deliberate, conservative type; I'm never going to be the person you call on, for speed runs. My healer horror stories are all one kind: healers (and anyone else who can do ranged DD) who forget my maximum range on Shield Lob is 15 yalms; or who just don't CARE - and start firing off ranged attacks over my head before I can get to the mobs and gather them in.
Then I get to hear the ZING as all the enmity lines arc over my head, converging on the impatient damage-dealer, and watch as the mobs run right past me to get to their tasty treat. Then I have to go into flurry/panic mode flashy-flashy-flashy stabbity stabbity stab to get the mob back.
I have a routine for DF now; I start every (low-level, 4-person) run with the spiel "Everyone PLEASE don't do *anything* until you see me Shield Lob and Flash..."
