Global statistics like damage, ctr and asi work consistently on every weapon.
But the stuff you want is too delicate to touch.
"Welp, I see the nice UVS For swordsmen, like ctr or asi"
CTR is nice and available to everything, gun, bombs and swords. Find a better argument. :p
Mag capacity would be broken as all hell and wouldn't be compatible with a lot of guns.
MSI while charging would be useless on most bombs as you already move at 93% speed while charging. (which is a barely noticable amount) It would only affect Graviton, BAB, Irontech, making it another useless "Family Damage Bonus" UV on most bombs.
