I meant "more" viable. I never really use it because the duration is so short and i need to be doing other things than applying chem spray, and once theres more than 3 stacks of fire on something while i need to repair other things, it starts to feel useless.
About the new meta, i do have a certain feeling that this gun might have piercing damage, because those seem to be lacking and it might change up some of the really common weapon combinations.
