Please make the Self-Revive manually activated, too often I find it being used in a situation I don't want to use it at all, especially in Elimination. For example I die right before we win the round and it gets wasted 2 seconds before their last person dies. Or if I'm outnumbered 3/4 to 1 and I don't want to use it I should have that choice.

Make it so that you can activate it within 5-10 seconds of dying. It can't be longer than that or you can just stay there until they move away and then come back to life. There also needs to be a limit so that rounds end as currently they don't until you revive automatically and die again (which can often take 5+ seconds before happens).
