There needs to be something in place to hold people accountable for their ability to play. I've come across some dps in 4 man dungeons where the warrior is out dpsing the mnk or black mage and all I can think is "Really?"
I'm all for helping people if they need to fine tune their rotations and such, but if you're showing no initiative to really learn the class I'm not going to sit there and spoon feed you as I have my own things to do. I've come across monks who just sit behind the boss and just spam their skills there.
