you can copy the entire game directory of each game and not have to worry about re-installing/updating the games once you have copied them back over, and they will work without issue.
IIRC when you do this with GW1 it actually adds itself back to the registry when you start the game if it doesn't find the proper registry keys (and I believe it changes them if the location of the EXE is different than before), if GW2 does the same then, as you said, there would be no issue at all doing this with GW2.
That being said, lots of software seems to be doing this now, even Steam, you can move the folder and downloaded games and when you launch it from the new directory it will correct its registry entries.
