I can think of only a few examples, and for the most part they share restrictions such as...
- Can only teleport to somewhere the caster has been before. Unless the BBEG let you in to use the restroom at one point, no 'porting in and ganking him while he's in the tub. Not even line of sight is sufficient, you have to have personally experienced the space in question.
- Can only teleport to one specifically pre-designated point at a time. You mark or bind the area, then you can go back there. Makes teleporting much more a defensive action, rarely offensive outside of the occasional elaborate ambush.
- Can only teleport to a significant location. Ley line nexus, teleport point, mystic gateway, etc. Sometimes teleportation is even restricted further in that you can only leave from one of these locations, as well.
