just a suggestion for future content, ability augments. some type of item that changes the way an ability works
example: a augment that changes the cone of the flamethrower from a long shooting stream to a wide fanning cone, this is just an example,
the idea isn't to change the stats or add a perk, but change the ability itself
This idea would fit with the philosophy they seem to be taking with the weapon components, with the shotgun adding an acid primer. It's a good idea that would add variety to builds
It seems like it would make more sense to just make a different flamethrower item in this particular case. However, something like Masterwork sigils with their own proc perks would be fun to play with.
