Cant advance california xp, recon drone and sensor ptoblem

issues im having i did all the challenges for the california unlocks and im now stuck at 7 completed tiers. Nothing i play seems to advance this at all. Will there be more challeneges before it ends to reach the last?

i also have a gripe with recon and tanks

tanks, why the heck when i need to bail out im deployed in the front where im being shot at just to be shot at lol

recon, when i deploy the drone its always facing behind me.  The wrong way. Why do i have to spin it around or lay the wrong way

Also recon, in duo or quad one of my biggest gripes is when u do something like put a motion sensor down it switches to your next gun. This is highly irritating in close quarters at end of the game when your 2nd gun is a sniper rifle and spur of the moment the game cycles it to a gun u can shoot once that doesnt register point blank. They need to stop auto weapon cycling and go back to the gun u were holding before u put a object down
