I agree with you on some parts i think the spam of Detection streaks and equipment is out of hand, it forces you and everyone else to use stealth perks which in turns slows the game down their is a few solutions:
1. Remove motion sensors from the game, having a pocket uav every time you spawn is stupid not only is it OP it makes the person who uses the device camp more as well.
2. Reduce the spy plane spam - either remove support or make it higher to reach and dont have two types of spy planes you can select in one run through of streaks ie: uav & advanced uav only have one.
3. An idea would be to reduce its effectiveness which i like as it punishes people who camp more than people moving which is have it so the person who calls in the spy plane gets a info from every sweep whilst team mates get info from evry second or third sweeps and naturally the more you call in the quicker it will be for everyone.
