Fencer should just do for single wielding what Hasso does for 2 handed weapons. Problem solved. But since the only job that uses 1 handed weapons and doesn't have dual wield 3+ natively is BST, Fencer will never be changed.

Could we meet half way, and just give BST dual wield 3 at 95 like every other 1 handed weapon user, and pretend fencer doesn't exist?
