Think groups are going to be bouncing around to players as each casts Fold Space? The tanker casts it, then the blaster for his nuke, then the stormie for hurricane, then whichever other characters have pbaoes they want to explode? That may not happen at all, but it seems like enemies could be pingponged a bit. Not everyone is going to be investing in the Teleport tree though, of course. It'll probably be fine. Kind of interesting thinking about this power going off multiple times per encounter, though.
