The problem with the advanced class is one misclick, and your stuck with the advanced class. There is no confirmation screen. I think there should be a comfirmation screen. In addition, there should be a way to switch between the advanced classes.
Also, there should be guild banks as well. I know the developers copied a lot of things from World of Warcraft, such as scheduled maintence days no crossfaction communication, monthly fee plans, naming policy, battlegrounds with evil faction winning most of the games, PVP servers with encouraged ganking, auction system, aggro sounds, flightpaths for taxis, having to learn riding skills that are outrageously expensive before using a speeder, with the riding skill price coping WOW, just to name a few.
I also thing that the price to learn riding skills is too much, and should be lowered.
