I've had no problems with this system. I followed the warnings they laid out back in 6.2's patch notes. (Find >> " official release of portraits " )Resetting my gearsets took little time and only messed with my hotbars a little. I didn't do anything with my plate since beta, aside from add a new background.

I went through a whole bunch of gear changes for my SMN and any change has stuck. I've been using different glamour plates for my casters and haven't had a problem.
