Oh, I find it hard not to argue, too. I hate it, but I can't stop doing it. I try, and sometimes I manage to tell myself not to post, to look away and let it move on un-commented-on. I probably hate it exactly because I can't help myself most of the time
Probably, or who knows, maybe it's possible to track teleportation? It's probably not a common skill, but I bet Twilight could do it so maybe some suitably powerful enemy could too.
Exactly, the point is that there's always something the bad guys can do to counter the good guys, even the Elements if you need to, until the end when they have to loose (unless you're writing the kind of story where the bad guys win)
