Will still improves their damage and it gives them defense on top of more slots to hold their shells which they do just fine. I'd actually say they have more problems with SP than they do with shells.

And you're generally missing the point of what I was saying because of most of what you said just goes into what I said.
Whether or not they need 1 or 2 different skill slots, I don't really care about that. What I was addressing is Grandpa's constant point about how mages "get everything" and other classes don't. Other classes don't need "everything" because that's not what their concept is about. The classes that have variety promote will scaling and make it so the stat isn't wasted on them. The ones that don't have variety or scale with will don't need it.
(Also, Prophylaxis and Sudden death are FAAAR from key to a BK's offense and defense. Let's not even pretend they're that useful. They also indirectly scale with defense more than anything, will just raises the threshold)

As it stands right now, every single melee class can function just fine with the amount of skill slots they have right now and there's no real issue with it. Like you guys are seriously acting like you can't equip all of the skills you need. I've got a level 42 Arb BK with 10 skill slots and I'll be getting more as I level. Considering the class combo, that's about as low as you'll get with skill slots. With those 10 I get all of the main arb skills that I'll actually use, steel mind, stalemate, and prophylaxis because I've got nothing better to get. Everything after that is just a bonus and pushes sub class further down the road of not actually being a subclass and just being a 2nd main class.
