I agree, the air force went into the predator program ill equipped and not ready. I dont think however, they were expecting such huge success and the increased demand from the program so soon. I heard they are trying to make it an actual career field, and not have pilots do double duty, but you know how long new programs take to get started.
Also, the pilots in the AOR have to account for wind conditions, etc. thats why they get it for the last 1000 feet, which sometimes isnt enough distance if there is a gap or delay in the transfer of communication.
They chose to make the pilots keep their current certs, because it is more expensive to have to re-certify someone. That requires more time in training, plus an additional pilot as a "trainer". So it makes sense to save money, yet they could just adjust their requirements for certification.
