Probably incompatibility because he mainly uses fire dust as ammo.

Probably because fire-based bullets are pretty effective in dealing damage. Ice Dust can immobilize, but it can't inflict any major damage outside of frostbite (which probably can't happen due to aura shenanigans) Lightning Dust can also deal damage, but it's more concentrated so it doesn't have AoE effects unlike fire dust. Wind Dust... is wind dust. It probably has more knockback capabilites than damage.

According to RT, utilization of elemental dust is not as easy as it appears, so some pipu prefer just going non-elemental since it doesn't cause too many problems. This is the distinction between Weiss and Ruby. Weiss has advanced knowledge in Dust utilization. Ruby does not and just shoots them ala Gravity Dust.

Ren's weapon of choice is fine. I think giving it elemental properties will break it due to its high rate of fire.
