Here's whats kind of fucked up about the whole Phoenix Five fixing the world thing.. if mutants ever actually cared about any of that, they could've easily done that before. How many weather controlling mutants are there? How many mutants capable of dismantling nuclear powers?
There've been mutants capable of controlling the entire world telepathically.. mutants capable of bending reality to their whims.. the Phoenix Five are doing something which, quite frankly, the X-Men could've probably done anyway throughout the years without the Phoenix force backing them. But they didn't.
They SHOULD be focusing on bringing mutants back, like Scott originally wanted, which started this whole fucking mess.. instead, they've become power hungry and want nothing more than to show their dominance over the planet.
