What about an AoE weapon with slight demobish effect and interference would affect the damage, so big blobs will receive more damage. Weapon would require Medium Chassis misc slot, I'm not sure if a small version of this could be easily balanced, limitation one per bot,  and maybe a couple of extension related to how many targets can be affected by this weapon and about the size of AoE.

I agree, PO is sitting on a creative gold mine.  The ship-to-ship weapons of SciFi and the Melee/"current" military weapons of shooters.

Tell me that you didn't at least kinda like Optimus Prime (as silly a movie as it was) as he whipped out his glowing metal sword thingy.

Yay artillery! Yay snipers! yay flamethrowers!  Only mountable in industry slots! Miners and harvesters to the front line!!!

dont say it to loud... i see an army of (drunk) mk2 argano/lairds celebrating their victory against some stray miner and solo-farmer on a global holiday like christmas...

I like the idea of a sniper firearm weapon .   Imagine if you will say 500% damage base , but ammo of 1.  It would rely on your reload extension for faster firing. Perhaps using special ammo for it. 
Or a weapon with Optimal range 100 but falloff 700.
We can throw ideas at the DEV's but ultimately they need to read these and then if they CHOOSE , implement them.

LoS though is tough call for most long range fights. Terrain can be a ***
