Thing is, even with 340% scaling, the damage is comparable (at best) to most offensive skills when you take SWA into account. It also makes them more limited, because maximizing your weapon of choice's SWA is easy, and it'll be equally effective for all weapon skills of that class, depending on the scaling, but for youkai skills, you need a larger variety of stats/equipment. Not to mention the amount of time required to level up the youkai; you can argue that, where balance is concerned, effort isn't a very relevant variable, but I think it has some value to consider.
