I can't stand seeing the recon drone come out just because people always seem to kill me just after it flashes me. Rinse and repeat for what seems like forever. It is a good KS for Support though. I used to try and ignore them but now I go out of my way to shoot them down. I like the concept of support killstreaks and although I didn't use them much in MW3 in my latter prestiges, I will miss having it out there in BO2.
