I never expect or think a computer RPG can emulate PnP. I am willing to turn a blind eye to such moments in the game too. But they have to be made convincingly enough in turn.
Which this event isnt.
Its a different subject but i only mentioned it because during it you can literally see Orivand shooting his beam of derp through the walls - in addition to other fabulous "reactions" such as not being able to notice someone teleported that elf away right in front of him and other magisters.
- teleport should never have been made available that early. And OR it should be inapplicable on anyone with magic armor too.
