Teleportation.

So many games have these built up scenes between good and evil, the heroes finally catch up to the antagonist, they have them cornered. The antagonist gives a monologue and then teleports away, immediately ruining the whole scene. We had to fight our way in, but you can just teleport out?

So much tension is lost in scenarios with teleporting, it's just a bad way to put 2 sides together and resolve it with nothing happening instead of writing an escape or literally anything.
