If ppl actually know how to play their job i don't mind if they haven't watched a vid or read a guide, though it is definitaly a bonus. that is for a PUG learning situation. In FC static/pt I expect everyone to at least have a basic idea of what will happen.

if ppl don't know how to tank/heal/damage at endgame, they should stay away and don't waste others time until they improve. it is one thing to struggle with new abilities while you are leveling but at endgame you better know your job. how good that someone can adjust to the situation of the content is another thing, but that is what learning is for.

But most ppl won't improve. They rather quit when given hints or been kick a few times than seek the fault by themself. and then go to the forums and call ppl elitist and toxic...
