Sharpshooter - I'm more of a fan of replacing the -5/+1dX where X is the die type of the weapon.
Greatweapon Master - I would rather replace the -5/+1X where X is the die type of the weapon. Greatsword 3d6, great axe 2d12...
These make the damage available but can limit it...
That is incredibly sensible. Gives a Paladin a reason to pick up a greataxe instead of defaulting to greatsword.
