So I have a really, super nifty thought for improving functionality of riggers / droners. What if you made enhancement slots for vehicles and made an item that allows you to upgrade them with a remote control rig, this way a droner can activate the vehicle and operate it from a short distance away, like a drone. Vehicles can be destroyed, and they're a big investment, though they're very hardy and rather large in comparison, you could use it for remote transport or remote collection. If the rigger is controlling the vehicle remotely, they could use it for mobile cover, or to protect themselves. It could be something like this:
Also, what if we introduced a system where a rigger can control more than one drone at a time? Lets say we used a device like a hack tool, which had slots for how many drones or vehicles you can control or switch to at once? You could have drone commands that have them come into formation, fire when the other drone fires, and converge their aiming on the ones reticle, allowing to improve firepower but still limit it based on the person's ability to aim at a target
