i do get that it would be faster to have a single "repair all" for all categories at once, but really does it save you that much time to make a diference? going through all of the categories will take a minute maybe 2. it just plains out speaks of lazyness.
of course, if you're using a npc for repairs, it will be more annoying, you will be hitting it at least twice as often than someone that can self repair. but then again, that is merely the player choice.

i would prefer they added a desynth all option or quick desynth over this ~.~;
