So I've been playing around with my killstreaks, cerberus and talon seem pretty powerful, and a good combination alongside UAV, in my opinion.
Finished a game last night at 33-1 with a 29 killstreak thanks to this setup. Controlling the cerburus which only requires a 7 killstreak to attain, generates me an average of five kills (ranging between 2 and 12 so far), and Talon gets me an average of 3.5, ranging between 1 and 7. So in many cases, cerburus leads right into Talon, and with a 7 killstreak I can add +4-19 kills to my streak (mean, 8.5).
Obviously a few things need to happen for this to work out, ideally, but it's been very consistent for me so far and I've had quite a number of matches with scores like 43-2, 33-1, 26-1, 47-6 etc. just in the last two days since switching to this scorestreak setup. And even on bad games where I've been mostly even, getting this up just once pushes me to to an extra 10 kills, usually into a 1.5-2.0 KDR. Not to mention, it provides tremendous amounts of control over B for your team to ensure you get the cap and ultimately, contributes significantly to the match outcome in Domination.
Works best in domination, sit your cerberus on B and use it as a 'turret' don't push into enemies too much else they'll rotate spawn, sit on the edge of their spawn overlooking the major exit points from B-ish area and you can mop them up as they approach B from spawn. Displacing their spawn is bad, as moving the cerburus is slow.
used it as my secondary weapon...
