If so then feel free to shoot me down, I have a thick skin. If not, then a companion/pet to fill in where you are weak.
Examples;
A sensor/EOD/black ops non combat drone. ("Run away little fella, I'm gonna to need you later to find out why these guys were willing to die, to keep me away from that safe.")
A piecemeal salvaged turret bot. (Immune to poison, good at wasting ammo, but its got your back.)
An armored Rathound or Railwolf complete with doggie backpack. (Can smell explosives, carry gear, and chew faces off. What is not to love about mans best post apocalyptic buddy?)
A Robo-Wastehound. (Just as good as a regular waste hound but you don't have to feel as bad when fido catches hot sniper lead with his face.)
Should be mortal and require significant investment for both stat points and currency to be effective. I know this is a tall order, but this would allow for challenges to be more demanding to specific access difficulty skills. Also would allow for viability of a greater range of non-conventional builds, with no need for investment of dev time to create lore behind them, you have the models and mechanics needed already, you would just have to adapt them for players to interact with them in a new way.
I wont hold my breath, but it would still be neat to see.
