I'm not sure about Ryu-Oh. I mean, by herself, yeah, if I use Andromeda with Sniper Shot. But both with Sol AND Ryu-Oh? That's... gonna hurt my damage output a whole ton, no?
Did run with Sol today (thanks Miracle ticket!), was notably easier. Still not a breeze, but considering that I lost 2 Hime throughout three runs, can't complain.
