I'm gonna agree to disagree on Morrison as I enjoyed his run (as an adult).
The main roster should remain the same for most of the run; however, every character doesn't need to be involved in every major arc. Daken being there would work because Daken fighting along side Cyclops specifically because he knows how Logan would feel and Cyke's allowing it regardless would make for an entertaining read. We'd have the tea (specifically Magneto) wary of Daken, Daken will be able to grow with 23 a bit (since she'd be with All-New) and the whole "clone is more important than son" story would do wonders for both characters. The "Wolverine on every team" bit is satire and making fun of the oversaturation of the character: two "Wolverines" being on the blue side while not actually being Wolverine who is still featured in the gold side books.
I like Frenzy; like with any character, she needs a consistent writer and main series to be featured in so that she may grow and gain a following. She's basically waning potenial and her role post-AvX should be capitalized on. The dynamic of she and Emma is what I want to read since both have similar backgrounds and it would parallel the Emma/Jean thing but have a totally different feel to it.
Rogue is my fave but I prefer she be wherever Storm & Psylocke are if she's to be in an X-Book.
He and Emma walked off and it was implied (though I remember her being blatant) that she would remove the alternate world memories.
