make the WP assists rather than direct kills.

because the people who would do that are just cowards.

I like the idea of drones as long as they are limited and can't be spammed for easy kills.

I think AI drones aka passive drones that follow you are would be fine as stat boosters, like faster shield regeneration within an xx area or other similar stats that can support the team. Like others have said, it should be heavy cpu/pg costs and require some dedicated skills to use and have limited health and function. This feels like a natural expansion to logi skill set as a possible way for a logi to support the team.

As far as remote controlled drones, they should be limited to spying, hacking or maybe scrambler drones to mask team movements. They should definitely have limited stats and range if implemented.

I am in support of this idea. As has already been pointed out in this thread, Killzone 3 is a perfect example of how to do AI drones well. An alternative could be the MAV from Battlefield 3, which could be remote controlled or AI, and spend its time searching for and lighting up enemies across the battlefield.

in my opinion it should be like the MAV off of BF because im pretty sure the drones arent very big

I did actually read on the drones you had posted, and honestly the UVAC sounds a lot like BF3's MAV, because you can "spot" people using the MAV which gives out their locations to your squad. If we're talking about just passive reconnaissance, then the scanning drone could simply pick out enemies the same way they're picked out by aiming at them. But that seems kind of superfluous in my opinion. So I say the drone's scanning should be increased somehow: maybe making every enemy on the drone's screen light up like a christmas tree, perhaps even having an outline of them appearing through walls or other barriers? I think that would make the drone's scanning quite useful, even if there were no armaments for it. And the one piloting the drone could receive a point bonus for every enemy killed that they had highlighted. I think this would make the drone very useful for coordinating things like precision strikes or orbital bombardments.

As for the ground drone, this, I think, could be useful, but the EOD bot in Battlefield is notoriously difficult to control. Aiming a gun with it would be hard. And honestly, the vehicle controls in this game make me a lot less inclined to drive one of them around than I otherwise would be, despite the awesomeness of drones themselves.

In addition to these two types I would also like to submit two more.

The first would be airborne, but much bigger, I think, than the simple scanning drone. I think we should separate the scanning drone from the combat aerial drone, both to avoid the one drone becoming OP and to give drone users a sense of choice, that they can decide which kind of drone they want to use without having to be restricted to only one air type. So this drone would have the same scanning capacity to a regular dropsuit, but would be able to fly around and engage ground targets. It could call down guided rockets, perhaps from the MCC, or use some sort of mounted blaster or mass driver. In my mind I see it as the tactician's drone from Killzone 3, which was controlled by AI, but I think allowing it to be remote-controlled is also viable.

The second kind of drone is a personal-defense type, also featured in Killzone 3 and used by the medic class. The personal defense drone was AI, and followed the medic about, opening fire on any enemies that came within range with a ninigun attached to its underbelly. The drone was very fragile, but was loyal almost to a fault, sticking with the medic while he bled out on the floor. I think this would be a very useful add-on for logi-users, perhaps even dropsuit-specific to them. The drone would follow the logi around, providing a bit of backup and extra firepower in lieu of protective squadmates. Improved versions of the drone could even fix the logi's armor or provide temporary shield hardening, or maybe even inject nanites to its downed master.
