Not only is there everything I stated, and this axe comment, and the comment from Cream Soda, but keep in mind there are other WSes that also have STR mods that need a nerf, by your logic. I don't think this WS (Shoha) needs a 2x ATK buff and I don't think it has one that high, but it does have some of an attack bonus. Guess what also gets an attack bonus? Most of the other merited WSes for jobs that need them due to having lower damage rating weapons. Holy crap, logic. Even more logic: they get negative or no bonus at 100tp and get positive bonuses a little higher than 100tp. I can also name a WS I never use at 100tp outside abyssea, I wait for 120, say hello to Blade: Hi.

BALANCEEEEEEEEE

Also: Merit some of the other 2 hand weaponskills to cap, properly gear them, and see what kind of damage you get out of them. Resolution is also an STR mod, and hits 5 times, hint hint.
