That, and Slydria's scaling suggestion looks more like a buff to Youkai damage.

It'd be a buff for Byakko specifically but that's only because Byakko has high STR and the example has high scaling due to Thunder Claw's downsides compared to other Youkai Skills. It'd be a different story for almost every other Youkai and more importantly, their Summoners who would need at least two stats to scale off of.

Anyway, if that's too fiddly then I'm all for just messing with the scaling amounts and having a Summoner penalty.
