Even if it is considered movement, the spell specifies you ignore physical barriers, so if you can "move" (i.e. teleport) through walls, why could you not teleport through enemies even if they have the blocking skill?
Because not all of us can read French. The English edition of the rules leaves out the part about ignoring physical barriers, relying on the implicit definition of "adjacent" (which is never concretely defined, though it is indirectly defined in the Wall Wrecker skill as ignoring barriers).
If the English edition of the rules/cards/skills were as good/clear as the French, there would certainly be 99% less hate flowing through the forums right now.
