ANET should add at least two custom mappable enchant cancelation hotkeys to the available command set. At least one key would cancel the earliest cast maintained enchantment, while a second would cancel the lastest. This would speed up certain operations like cancelling Aura of Displacement, Recall, etc.
I ran a search and didn't find any previous results, so if this has been suggested before, my apologies. Another user in a different forum asked if this feature existed. The answer seems to be "no," but why shouldn't it be part of the game? I know it's not an earth-shattering change... more of a preference and convenience issue that allows GW players to have more keyboard control and efficiency options.
