Interesting, appreciate the information. I'm glad they are going to limit it, as an "unlimited teleport" doesn't really seem to fit with the abilities of the rest of the models. I like how the "supernatural" stuff is present, but not overwhelming.
Just wanted to chime in here re: this point... When the KS was first going on, Nick from RRG described the game as being cinematic, meaning that during a game, the "camera" zooms in on one part of the fighting while you activate your model and that's where the focus is. Then the camera zooms in on another part of the fight when another model activates and so on. I've always thought of it like the battle of Helm's Deep in the second LOTR movie: first, you see Aragorn swinging his sword at some Uruk Hai, then Gimli, then Legolas, then back to Aragorn, etc....
With that in mind, I interpreted the original (now corrected) reading of Interdict as the "camera" zooming in on Theo sprinting across the arena to assist her teammate rather than some magical teleportation. I think that works for lots of the special skill descriptions too - less some mystic power and more a representation of some action movie action.
