Remember that a MAU costs much more than regular potions per HP point. MAU also hides the weapon and the armor the user is wearing, so while you say it has too much damage, you prob don't see the +5 or +6 weapon under the suit. One last thing is, ARs have a MUCH, MUCH harder time leveling up. Expert melee and range skills, basic force, lowest hp class in the game, no class buff outside the armor... nothing helps the drivers level up; instead, ARs get less exp than regular chars if riding their own class's specialty. ACC launchers and Coras have the same exp... Coras have to deal with animus leveling, but not accs. ALSO: MAUs can't use rune or potions while riding. We have to get off, use it, and ride back.
