Pyrana Prime worth investing forma?

[deplorable gollompus]

I've already built and potato'd the Pyrana Prime, but words cannot express how disappointing it is. It's useless against anything other than trash mobs, because you can't activate its passive which actually makes it acceptable for an MR13 weapon for about 3 seconds because it takes so long to kill anything above like, level 50-60. I'm wondering if forma'ing it will make it better, but I kinda doubt it. I just want it to be actually excusable considering its MR requirement and the passive is fun.

Have you already invested a Catalyst into it? That alone should really prove if a weapon is worth it or not. For example, I absolutely abhorred leveling the Dragkoon back when I did it for the Mastery. I didn't potato it of course, so it was a disgusting base 30 capacity ( and this was before MR affected equipment's mod capacity before leveling it).

I eventually rebuilt it to keep it for good, and it's become one of my favorite shotguns after I threw a catalyst on it.

Yeah, I potato'd it just because it's a fun weapon that I would very much, uh, pardon the phrasing, like to like.

status still isnt great for removing armor but for now it works.
still debating on whether to just replace it with 90% elemental and swap scorch for sharpened bullets.
