Good player will do their research on endgame dungeons and fights. Will make an attempt will property gear themselves and have adequate gear for what they are trying to accomplish.

Bad player is the type of player who doesn't research their class, will queue up for AK in DF having all AF and a level 40 weapon level 20-30 accessories expect to be carried and have everything explained, crys about elitists when they get called out for gear.
