So I Need Some Weapon Advice

[cmacq]

I'm pretty much a confirmed Ignis Wraith guy. I have tried/forma'd up many other weapons but keep coming back to my favorite flame thrower. Had a look at the riven auctions and the price for one I can re-roll (I have lots of kuva) is really not bad. Is it worth it on this weapon (with a 1 star dispo)? If so what should I look for in stats?

 

TIA

1* dispo is generally not worth it for damage rolls. However, crit rolls might be worth it if you can boost the roll with a harmless negative stat.
