One thing that's neat to me about BattleCON: Devastation is that despite the anime style it doesn't seem to be super fanservice heavy. If anything, the style looks like an oldschool manga or something.
I'd say most all of the female characters have reasonable outfits, and the only really revealing outfit is for a character who's intended to seduce and petrify enemies.
I'd say it's very tastefully done too, Nokomento did a great job of unifying the characters under a consistent style. If you compare anything from the original print of War of Indines to Devastation of Indines it's night and day. The only character that sticks out as fan service to me is a very minor one (One of Gerard's mercenaries, but I think they're supposed to be archtype-driven and a bit cartoonish anyway).
