I don't have a problem with Batmen, per se, or anthromorphic races in general, as long as they're well done. I mean, really, you've got Orcs? Goblins? Giants, dragons, demons, and medusae? How original. I don't care about original race or monster ideas, just execution.
And they really botched the execution on the Desmodu. "Ok, we've got a race of bats, now what?"
"Lets make them as big as Ogres!"
"Strong as Giants, yeah!"
"None of that flying, agile, bat-like crap for these guys!"
"Ooh, add some poorly explained sonic attacks!"
"You mean like stunning shrieks? Or echolocation?"
"Waaaay too plausible. Lets have them do weird buff-debuff effects, and explain it away as sub-sonic"
"I know, give them a goofy weapon!"
"Brilliant! Make it a double weapon. You can never have too many uniquely goofy double weapons."
"Hmmm...it's a good start, but not weird enough. We need more."
"Give them batwires! Like Batman!"
"And silly Alchemy weapons these great, hulking, melee brutes will never need!"
"Excellent! Now get me an artist who can really ham it up, and we've got a new race everyone will love!"
(all) "Yay!"
