Okay, some of the New Mutants may be lower level than 350. OTOH, the more experienced and powerful ones, like Magma and Magik, would be at least that, maybe more.
And I stick with my assessment of the Teen Titans, though perhaps I should have specified Wolfman/Perez New Teen Titans.
As for powerful heroes, yeah, it'd be nice to see the stats for some of them. We've got three that are 600+ points, but there ought to be at least a couple canon 700-800 point heroes. Meteorman III *should* have been in the first group at least. . . *grumblegrumble*
