I know that slag will not stack, and a slag weapon will not deal extra damage to enemies that have been coated in slag. My question is, will the shots that don't slag (from the same gun) deal more damage? Would Critical Hits deal more damage? Or am I better off ditching it for a corrosive version of the gun?
If it does deal more damage, which would be the better gun? (They both have the exact same stats, except one is slag, and one is corrosive.)
