And?
When I play UAVOP, I find the most effective use of my time by far is using the UCAV in collaboration with airborne CAS, one by one, lazing and destroying every piece of amour active within the AO. The Falcon might present it's own variety of interesting options lazing and providing CAS had I purchased the Apex DLC, and as far as I am concerned, the Darter is far inferior to any of the UAV variants available.
Stompers are odd, too say the least. When it comes to providing fire support for infantry on the ground, it can be somewhat useful from a fixed position on overwatch, however it's performance in the thick of combat had been sub-par. Lord have mercy on you if you come across any enemy amour. I have found the experience to be much more enjoyable from the seat of a Hunter, of which is able to transport both the ability to repair it's self and other friendly assets as well as a gunner capable of keeping watch while I sit on the UAV Terminal. Doesn't hurt that it is also much, much faster as well.
With regards to UAVOP leaning too far towards CAS and disregarding their traditional role of the invisible recon element, I have found it comes down to the individual in the slot at the time. Provided they follow the aviation rules and do not engage enemy amour without permission, I believe that they are more of an asset to the pilots in the air (having dealt with AAA positions) rather than a hindrance to infantry on the ground.
Do you feel differently?
