Hey, what about a reverse worm hole? Something that teleports you BEHIND the guy behind you! I know, you can just brake, but sometimes people see that (especially if you're way ahead of them) and do the same accordingly. For this to work it would be something instant cast and with no apparent visual effect, so people cannot expect that it's going to happen and you get to keep your position because -if you can time it properly- you can keep racing as you retain your speed and direction instead of having to start again after you brake to a stop.
Perhaps, since it's not really a "weapon" as it is a bit damaging for you, it can be made so that you can activate it if you have two homing missiles and fire them simultaneously while pressing a modifier key of some sort (because sometimes you still want to be able to fire two homers simultaneously and not be teleported).
oh and of course the leader missile must be really precise as you might be wanting to teleport right a split second before being hit, and the guy behind you is already laughing at the idea that you are about to get wasted, but then you teleport and the leader missile, which an instant before was aming for that other player, now suddenly turns to you and before you realize what happened it's already too late.
So, like, braking for other to take the beating, but on steroids!
Oh yeah? I'm so boring that
