As an aside, his stock has seriously depreciated lately; there are now four teleporters attached to the overall X-Men (him, Pixie, Illyana, now Cloak), and he's got the least range and least capacity of any of them.
True, but two of the other three run the risk of their passengers being eaten by creatures/forces in their medium of transport. And Pixie has to yell out a multi-syllabic incantation before each use of her power-that can't work smoothly more than a couple of times in a given fight before someone realizes it might be a good idea to clock her as soon as she starts chanting.
