still worth it to me, i do UAV for quick XP, sentry gun and care package...i seldom get the 7+ kill streaks, so this works best for me...i love getting 2 sentry guns and holding down an area.
btw, i just found out you can shoot down UAV's and counter UAV's...worth 100 points, same as killing a sentry gun or chopper.
i'll be on PS3 from about 6-10 tonight...someone hit me up if you guys want to get a TDM party going. i got an invite last night but had my girlfriends little brother over playing on my account, sorry, really wanted to play.
