Best upgrade for grenade launcher?

[Diva]

Hello

I love the grenade launcher and would like to improve it but I don't know which one to choose. So I need your opinions.
The improvement with gravity seems pretty good to me because it does a lot of damage (52).

Thank you

Up to you really...you're also able to craft multiple grenade launchers and upgrade them differently. Right now the game is being super evil to me and won't let me finish the damn blueprint for this weapon, lol

But yeah if the option is there, I'd probably go with fire or something.
