A slight variation of enileph's Nevermore it adds on an extra JJ as well as 2 MGs with 1 ton of ammo. The 30% range quirk for this little birdy makes the PPCs bite down hard from over 700 meters away, and the added help of the MGs for close skirmishes ensure you are not completely defenseless. you could of course swap to ER PPCs and increase that range to over 1 km with the added heat if you are good at heat management.
Lol, this thing looks hilarious. I'd switch out for Large Pulse lasers though, simply because of the Laser quirks. That'll also turn it into the "Wubbing bird"
I tried that but i do enjoy the punch from the PPCs and watching the opposing assault flail around looking for the heavy that shot them only to see my dust cloud.
