Kills count as 100 points.
oh so the kills don't count at all. Eh
For a point of reference, in Black Ops you had to get 3 kills to get the UAV. Now if all you do is worry about your K:D, then it would take you 5-6 kills to get it.
I play domination 99% of the time and I love how they did it this time around. Now people actually try to help take flags. They did in Black Ops occasionally, but mostly people just cared about their K:D. Some still play like that, but to really be good in this game now you have to actually help your team. Great move.
