Oh wait I remember now, yeah it had a pathetic low range, slow bullet travel time and atrocious cone of fire, it had this weapon after the Gauss as a nerf before it got completely removed and the 2nd shield got removed too.
To the buff topic either do the following:
1 Decrease price to 3000, don't touch stats.
2 Return the twin shield design and improve the drone reconstruction, more slots and lower cooldown between drone death and rebuilding.
3 Give it a strong Outlaw-like weapon as a form of non-drone attack/self-defense, nerf drones if this design turns out to be too OP(it really shouldn't).
Stats could go something like this
Damage: 100
Slow Damage: 300
Reload time (s): 1.0
Damage per second: 100+300
Range (elmo): 350 (shield area size)
Area of Effect (elmo): 100 (2.75 smaller than Outlaw)
Projectile Speed (elmo/s): 500 (Twice the Outlaw, to give weight to the pulse due to size difference)
Though even this seems like only a stop-gap measure as it only prevents scythe/raider rushes working against it, but I don't think that's a problem since any non-light AA will literally shred it in open ground.
This is however where Funnelweb being a spider comes in handy since it's pulse weapon works through walls and makes it actually viable to use on hill/mountain maps and is prevented from being a too OP unit by the presence of it's shield making it unable to cloak and highly visible.
