Im finding alot of the later killstreaks to be very laclustre, especially when they are garnering 5 kills for 1400+ points.
I'd say that despite the bashing it gets. the VTOL warship is the one I do best with, but it is very dependant on the lobby. Sometimes If it isnt shopt down I can get 16-20 kills with it, but on the other hand if the enemies are using blackhats and hacking me, ive had it go down in 7 seconds only getting 3 kills, not very rewarding for 1600 points. The lodestar is in the same boat, good when no-one hacks it, but man its so easy to take down.
I find the dogs to be very bad in this game. They move slowly and they have so little health its unbeivable. On to[p of that, most maps have ladders, or sections of the map where dogs cant get too, making them useless. I mean, wtf man why design maps just to screw with the upper killstreaks?
Warthog rarely gets me more than 4-6 kills, which again isnt worth it when it takes 1400 points to summon.
I cannot comment on swarm since i havent got one.
VSAT is literally the best streak in the game. 1200 points for a quote, unquote "radar hack". Best part is, that you cannot avoid it, once its up, you're boned unless you have an EMP in your back pocket (and lol asif anyone runs this). The CUAV is just a temporary stall since it gets shot down so easily, and again, i dont see that many of them floating around.
EMP is pretty nice for gaining score towards stuff, ive used it some times and gained 300 points jst from destroying UAVS, Guardians etc.
