They are fine and viable just the way they are now.
However true that may be, I don't really... care. There were already other guns that very much played the same roles that they do now. Their split damage was something of a novelty for me and I think for others too, and, y'know, split damage. I liked being able to use a shadow gun that was effective against beasts or an elemental gun that was effective against fiends.
No no it's okay i'll look in to your thread now
