Did you know not performing as you think another player should in a group

You are kicking people for being new in a place that is created for new people. What a giant contradiction.

See, here is where your argument doesn't fit my situation at all. This Black Mage was not new. He was level 70 running relevant endgame content. You don't get to that level not knowing what the core mechanics of your job are, even if you just spam Palace of the Dead from 1-70. When you willingly play counter intuitive to how the job is supposed to work, you make it that much harder on everyone else in the group. Had the Blm said something along the lines of not knowing exactly what he was doing, my party would have given him a crash course on how it's supposed to work. But well, you know how he responded. It had nothing to do with how long the dungeon would take- rather that we may as well have had only one dps to begin with, and we kicked him because a bad dps is one thing, but a bad dps with a shitty attitude is out of the question.
