Ok, I know what you're saying about the whole "I got revived only to get my head blown off thing," I get that. BUT, you can't really blame snipers for that. As a sniper in this game, and someone who does this (as well as it has happened to me) the issue isn't the sniper, but rather instead of having a over-shield (with apparently no armor boost in the head area), players being revived should have at least a two/three second immunity. The idea is not to let the other team get a revive at all, so killing a guys three seconds after he's revived isn't, or shouldn't be a hard task.
