For balance sake (And also that Dev brought it up in a bug report) I think that beast youkai and beast type players/monsters should be seperate for multiple reasons.

1.) Judgement blade's interaction can potentially nuke people who aren't even installed with youkai (more on this in a later point)
2.) Can cause troubles when interacting with GM Monsters.
3.) As brought up before, anyone with Bands of the Chimera equipped will be unfairly nuked by certain skills that do more damage to youkai (Mythslayer's effect, Judgement Blade, Youkai Tamer)

As I do think bands of the chimera does need its downside, that is currently in the form of Ranger's 15% bonus damage vs beasts, Hunting Bow's potential and also the beast aspect in your legend extension.

That said you can easily navigate around this by making two beast type races, one for Youkai/Black Beasts and one for players/Vorpal Rabbits/Scarebears
