There is a very expansive range of game play in GW2 including dungeon raiding and pvp. In my opinion having the ability to save more than one spec and having the ability to change them when each occasion calls would add much needed simplicity. Since there is already an option to switch from DPS armor to town clothes I really don’t see any problem implementing this. Its a giant pain finding your armor in the hero tab’s bags every time being that they change consistently when you obtain any new armor, weapons or enchantments.
