The preview of it's update actually looks fun. I love when weapons have alt-fires as it gives you a little bit more to think about during combat situations. The more options the better in my opinion. Maybe instead of the weapon doing bonus damage to all Cabal you could make it do bonus damage specifically to Cabal Gladiators (hell, give it a firefly effect upon killing them). That way you could make the perk stronger so it's noticeable and it won't make things too easy because the other Cabal will still be tough. Those Gladiators are annoyingly tanky so an exotic which remedies that would be an appreciated one.
