The ability to save specialization builds for quick switching would be great addition to this game. With a feature like this, a player could quickly switch roles while running through a dungeon or waiting in the PvP queue for the next match(though speed isn’t a necessity for the latter), without having to navigate the interface or possibly making an error in their selection. It would be especially useful in dungeons, where you have to worry about npc’s harassing you and possibly impatient party members.
