I should of said "learn to accept a revive properly."
Even when you get killed again, you still accept the revive. I've gotten killed in hot spots like lockers on Metro, and I got revived and killed right away 5-10 times in a row many times. Worst case, you end up staying dead, and the enemy had to waste a lot of time and ammo keeping you down. Best case, you come out of the revive properly (like you should every time you get revived; see video above) and are able to kill an enemy. Sometimes the enemy ignores you and shoots the active teammates of yours first, thinking this guy just got revived, his pistol isn't a real threat. Then you get to unload your primary on them. I've had this turn out to be devastating for the enemy, especially if I was running around with a bipod pro LMG.
