a look at the game universe's physics
Why is redemption even in the game? I won't even begin to talk about its abuse by players. Taking into account the physics of the Natural Selection game universe, redemption shouldn't be possible. Come on, you can't expect me to believe that aliens have evolved a technology similar to phase gates that is embedded entirely in their flesh? How can an alien just dissapear like that? Aliens already have numerous belieable evolutionary features that boost adrenaline production, increase the sensitivity of the olfactory nerves, and allow aliens to act like chameleons. These are all logical and believable characteristics of a feral, animalistic species like the Khaara. But wait, in addition to all of these physical traits we have one that allows one of these animals to somehow magically warp the fabric of space and time to their whim, transporting themselves to safety. It just dosen't fit.
Redemption should be removed not only because its an incredibly annoying skill, but it's completely unbelievable (even in this science fiction type universe). A huge alien can't warp instantly to a location without the aid of technology.
I might consider changing my mind if someone can give me a reasonable, believable explanation on how it can work in the game universe.
