Too much villian repetition brings up the question as to why these individuals are escaping custody or coming back from the dead so often. Magneto shouldn't come back too often as a break out would look really bad for SHEILD, and really there's only so much you can do with him, as in the end he's a violent fanatic, he can either reform, alternately harden and soften his ideas unendingly (as he seemd to do in 616) or go on a rampage to end all rampages get killed then come back again. Morisson did the right thing in New X-Men, and Millar highlighted the same flaw in his stories, Magneto is an inhernet, and pathetic contradiction, he claims to be the new man but is stuck in the basest most primitive side of the human nature he claims to be free of. He's a bit of a one trick pony and it takes a good writer to work with that to get a good story. And a lot of X-Men villians are fairly one dimensional - though when you think about it there haven't been that many and of those most are dead. Proteus appears to be street pizza (though theres a slight possibility he might come back) Wraith is dead (though Weapon X has a greater potential shelf life), The Hellfire Club is quite literally toast. And aside from Sinsiter and the looming background threat of maybe more Sentinels at a later date (officially sanctioned or otherwise) that's about it folks, there's not a whole lot to repeat. And quite frankly repetition gets boring. Less rehash and more fresh Ultimate redos.
