I was skill leveling my proffession because needed to train more after a few casts. Dalaran has auction house for engineers, arena queue, wg queue, trainers that people need( if someone is jc and wants to train, hes going Dalaran, train, and then craft near the trainer so he can train again after a few casts) He can't just go Dalaran, train and go IF, cause in a few casts he will most likely needs to go back in Dalaran but his HS is on cd. Not to mention people that fish in sewers for achievement or people leveling cooking. I dont deny the lag in Dalaran and that there are so many players, but it is what it is and so was on retail. Everything in Dalaran was made to be used by players. Dalaran had lag on retail too even if there were fewer players. If we could learn proff skills over 375 in IF, if we could go to ICC from IF, if we could fish the Rat from if, etc, we would stay in IF for the sake of lag!
