Hi,
Having seen last update that included lots of variant for existing guns, it revived in me the dream of using the quick sword known as the cutter. I've always loved that sword and it was my very first 5* (dread venom striker) but since the damage is 'normal' it is unusable; indeed compared to an appropriate weapon type for the monster you are currently fighting the lack in damage is far too great to even consider the cutters (the only point was to poison target, but from a long time now there are better ways to do it)
So my suggestion would be for a piercing sword in the line. Although we could well hope for all 3 types to be considered I believe piercing to fit better a swift style.
Normal weapons are not unusable, just not as efficient as others
The Iron Slug, Nitronome, Leviathan Blade, and Volcanic Pepperbox are fine examples of good Normal weapons
