This batch isn't that great right?
I'd call it average. No real standout characters, unless you have Corazon and want to cheese the hell out of every training forest, in which case you'll want to find yourself an Elizabello.
Cavendish looks like he'd be really fun to use since he's kind of a three-color legend, even if he favors the QCK side of things. Probably on the lower end of the legend power scale, but I think he'd be super useful for some colo stages (which makes sense story-wise).
Suleiman's great for slasher teams thanks to his stats and ability to give two matching orbs, but he's basically just a beatstick.
Orlumbus looks pretty meh unless you're running a stage with a lot of Block orbs.
Dr. Robotnik (or Dagama, whatever) gives Global another Paralysis healer, which is nice (especially since we're still far off from fortnight units who can heal it).
Elizabello, as mentioned, is mostly used for zombie teams, though he's got pretty solid stats as well.
Ideo might be the best general unit here, since he's got a solid captain ability (similar to 3D2Y Sanji but for Fighters) and can be a booster for Fighters or Shooters.
I would mention that I'd consider the next four RR batches significantly better than this one, if that influences anyone's pulling. I'm probably only going to do a couple here.
