1. Marvel just doesn't give a sh*t.
They don't care about continuity. They don't care about quality. The only thing they seem to care about is having yet another reason to put wolverine in a comic. Little to no effort was put forth into this event. In Avengers: X-Sanction Cable came from the future and stated if the avengers got Hope the world would end. And that Scott needed to protect her to keep the planet safe. Such a perfect.. selfless reason to keep Hope from The Avengers. Why wasn't this used in the main story? What happened to Cable who said he would be there to help? Instead they write Scott and Steve out of character to give a forced and irrational reason for these two teams to fight.
Rachel Summers the host for the Phoenix force for years, why didn't anyone think to have her train Hope? Oh that's right they were too busy saying how no one could control the PF. But wait one of the first things Jean Grey did when she became the host of the Phoenix Force was save the entire universe. The original reason given for Jean Grey turning evil was because of The Hellfire Clubs manipulating Jean made her go insane. This was later retconned into The PF created a double of Jean Grey's body and it was the one doing all those things. Either way Wolverines justification and reasoning for all of this is..well...incorrect. Jean grey in Endsong Jean strips the PF from Emma Frost, becomes the White Queen of The Crown and disappears in full control of the entity. What happened to Jean and The PF bonding together? Why is the PF suddenly not one with jean anymore and going around blowing up planets?
Wouldn't it have made more since if the 5 Lights or the 4 remaining lights and Hope becoming the Phoenix 5? The PF did create them after all. It would have given The Lights something to do other than be punching bags for Thor. I mean Christ what was the point of making a big deal about these mutants being born post M-Day if you do nothing with them? And then Have A vs X end with more mutants being created? They've pretty much means they've been irrelevant their entire creation. The Extinction team crossing the line to protect them would have made more sense than the Avengers selectively choosing who belongs and who doesn't belong in a cell/wanted. Magneto didnt have the PF power and he even helped the Avengers in the final fight. Yet he's on the wanted list with the rest of the mutants who weren't in control? The avengers were in control of their actions when they repeatedly invaded the homes of God while attacking children and kidnapping their messiah. No Consequences. The folks over at Marvel just dont give a sh*t.
