Looks better, though, actually, Spirit warlord was probably good at a +2 or +3; +5 is a pretty huge bonus, although as a capstone, it's justifiable. The weapon abilities are nice, and it's chassis is improved. It won't be hitting super heavily offensively, but it's got a wide variety of abilities it can change every once in a while, so it's at least fairly within the +0 PrC area. I'd definitely buff the Acolyte of Archangels feat, though.
