So, instead of Kill/Score/Point streaks I propose this idea to (hopefully) improve the game. Essentially they are similar to score streaks in the sense the player accumulates score for various actions in game such as capturing the objective, assists and kills but with these 3 key differences.

1. They don't reset upon death
I know this makes the rewards idea sound like Support, but the score requirement for them would be raised in accordance to keep medium-high tier reward out of reach of bad players

2. Bonuses are awarded for good play
For better or lucky players you be granted a bonus for better play. For example chaining consecutive kills without dying will give you a small amount of extra score per kill the bigger your gun streak the greater the bonus will be. This allows better players to get their rewards faster. Other bonuses would include getting Double and Triple kills and even headshots.

3. You can choose perks and other things as well
Along side with bog standard streaks such as UAVs, Airstrikes etc.. You can also select perks or double experience to be rewarded with.
