[Snake]

Firthrower could have more SKI than STR. The STR scaling is what makes it not as viable for Gunners, to begin with. Or a 40% SKI/40% WIL/40% GUI for it would make that one of the most unique weapons.

Personally I think they can get that much, because you cannot change its damage type from Fire to Pierce, and Fire is easier resistable than the latter, so it will be fine.
