Bishop/Priest at Bosses - Hardest wroker?

What annoys me is when my party members don't think I know when to HS at bosses. When they stray away from the party and complain about not getting dispelled/HSed it becomes very annoying. I've attended many, many zruns under a number of hosts, and many of them have had first time runners who think they're more experienced than they really are. A few days ago, I witnessed (but did not attend) a zrun that my girlfriend (DK) had attended. I distinctly remember one other DK who was sizing himself up against everyone else's "inexperience." Too bad he and most everyone else (aside from my girlfriend, of course xd) forgot their all-cures, and that run eventually failed because everybody just assumed that bishops never disconnect. I should just as much assume attackers never die, and not put any points into revive.
