Yeah, the Wedding Issue & X-Men #25 are great books. Just plain good storytelling and character writitng, and yeah- that whole Wolvie/Magneto thing was fucking intense for the time. As a kid, I was like "HOLY SHIT!"
Nicieza also deserves credit for making Cable a real character. Under Liefeld, he was just a grouch and a bad-ass, nothing more. Nicieza basically made him a father figure and gave him real depth. He did some great stuff under Cannonball too, even if he DID continue to fuck up Moonstar with her retarded storyline (why would a minor-league team like the Mutant Liberation Front need a "mole" that would actively commit horrible crimes?).
He also did the same to Shatterstar, and made both him & Rictor interesting characters (giving Peter David the idea to make them butt-buddies, which fits PERFECTLY with their X-Force characterization).
The X-Force run often gets forgotten these days, because it doesn't really "matter" in the long run (most of the characters were minor, Sam got a personality/experience revamp the SECOND he joined Lobdell's Uncanny group, Cable did more stuff in his solo book), but I actually like it more than the X-Men books at the time.
Did Lobdell really hate the Rasputins? Nicieza's the guy who offed Piotr's parents in Russia, and Lobdell DID write that cool scene where Colossus went berserk and fucked up that bitch of a villain Fitzroy because his sister was dying and Fitzroy just got in his way. It wouldn't surprise me, though- FUCK LOBDELL. I can't think of a single person who did more damage to the X-Men.
