Why can't we have a gear for each class we level? Having a this small inventory and being able to play so many classes at the same time is contradictory. What's the point of being able to play everything at once if you have to go back to your retainer for half your class changes? The only really point I can see would be to incite players not to change classes too often.... which is certainly not the current orientation of the game, right?

A dedicated gear panels would be a nice improvement, but would not suit the current class system. Having multiple gear panels (relative to the number of class level to a certain rank?) and the ability to switch of panel when switching of class would feel really adequate here.
