Teleport - cheat?

Teleport - cheat?

Anonymous

Hello

Teleport skill looks like cheat. On brothers lair map, when you must kill three powerful mages, you can open all but one door (with statues), teleport to mages, anger them and teleport back. Character can shot through the doors, he can kill all mages without problems with ranged attack.

This looks unbalanced, especially compared to melee character? Maybe create some teleport-free zones that can be deactivated after some trigger?

P.S. Sorry for my English, it's poor.
