Why the Pave Low? Because the Emergency Airdrop is beyond risky and something I only use for challenges. There's so much that can happen. You do not know which way your packages are gonna fall. I've had 3 of mine get over a barrier because of the random way they're dropped. Adding onto that, it gives away your position and takes you out of the game for a good deal of time. I chose the killstreaks that I did because I'm not busy with my Predator or Chopper Gunner. I'm immobile and chances are, I'll be found.
Even worse, theft. It can get stolen because my position is given away or a teammate can be in a better position for the good ones and steal it himself. On another note, it's entirely chance. Doesn't mean I always get something good. Not only that, it doesn't build toward another streak. I also find that the packages will kill you if they hit a slope and bounce. Care Packages are just not worth it to me. The Pave Low is just as easy to get. With it, I'm not out of the game and I can rush a spawn safely while building kills as they try to both shoot it down or hide.
Obvious retort;
BUT
YOU CAN GET A CHOPPER GUNNER OUT OF IT <c
That is an undeserved killstreak. Nothing more than a Harrier should come from an EAD.
EDIT: fffffffff of course the 11 streaks are the best are you kidding me? Flares, a good amount of time on maps, ridiculous killing power you control. YOU CONTROL. That alone makes it the best.
EDIT 2: Oh wait, misunderstood what you said. I don't use an 11 streak because like I said. I don't like being out of the game. I use air support so I can keep moving and I'm not on my computer playing ****.
