Crucible Revive Head Snipes

Ever been sniped right after being revived in Trials or Skirmish? Ever rage at it? I have recently discovered for myself how to do it and also how to avoid it. To do it it's simple. It's all about timing. Just aim at the red ghost with a high impact sniper (LDR is confirmed) and count 1, 2, shoot after revive. To avoid it just simply press crouch ON REVIVE. Slide or blink for good measure but there is my tip of the year, hope this is useful.
