Why I don't think Assassin will be an issue.
Think about it guys. Specialist Strike Package=no air support. **** Strike Package=mostly streaks that assassin can't counter. UAV won't be used as much on this package as most people are kill wh***s.
Which brings me to the Support Strike Package. First off they bumped UAV up to four kills/points and counter UAV up to 5. The next streak in line is SAM turret at 8. You will need to get 12 kills just to get a second UAV. Also the advanced UAV is nowhere near as good as the Blackbird. It still functions like a reg UAV. It isn't constant.
Recon Drones, Marksman, and Recon(perk) can all mark targets even if wearing assassin. Add to this the usefullness of perks such as Overkill, Quickdraw, Hardline, and Blast Shield people will realize Assassin isn't the all powerful perk that they thought.
So if you wanna be that guy who strictly uses Assassin be my guest. But you better have blind eye on as well. Which means no Sleight of Hand, Scavenger, or Extreme Conditioning.
There will be less UAV's in the air which will also help people to not rely on the HUD as much.
