I think that IW made the right move by making kill streaks into point streaks and basically anything you do now adds to that, so getting objectives, shooting down UAV's and counter UAV's ( holy shit how many people dont do this is unreal ) and air support now only help you that much more to get your point streaks.
I look forward to using the support point streaks, and I love how you can cycle threw them now too FINALLY!!!! All I can say is advanced UAV then stealth bomber is going to be fun.
