I don’t like this idea. FD is supposed to be primarily a wallpierce weapon; if you want to kill someone with true melee you can do it by swapping to a different weapon. If luring people into the blade is useless, why are you trying to do it instead of using FD for its intended purpose?
I do intend to mainly use it for its intended purpose, I mainly suggested to make the blade more rewarding while the projectile deals about the same amount of damage it dealt before.
