Motivating high levels to keep playing.

Alot of people grow bored of the game and stop spending money on it and quit, How about A new Gp crate that the grand prize is a permanent thingy that replaces granade and primary slots, and it calls in a 30 second nighthawk helicopter that supports your team with bullet fire, it doesent effect team death macth score, you will respawn if killed by the nighthawk, the person who called it wont get any kills but gets +5 exp per kill, the helicopter shows up on everyone including enemy radar, the helicopters hp is 800, killing it will give extra exp. And lastly even if you win the grand prize you have to be at least a SFC to use it or else you cant equip it.
