See Indeed for even a parts of your points like Wanda Not being used in the Comics we can agree upon, so Their is Common Ground their is to have.
Also I remember you and me
Ferro where in more agreement then disagreement over the Empyre X-men stuff as well hoping it go somewhere but they flopped on that it seemed by the end, which just dispointed those hoping for more if they where finally going their.
I don't think it is even a Matter of Perspective or Want, more that the only way to do a Final Book about this whole Wanda and X-Men debate would need to be taken Seriously by Marvel and be the conclusion of it in the end that sets good for both parts of the Fandom, Wanda Fans and X-Men Fans.
But I also believe their are Plenty of X-Fans and I Know Plenty that are also Loving Wanda Fans too, Me Included Allot!
We want to see it work out for both sides cause any divide while we debate it's logic and points at times want it to come to an end as well so any story that pleases both sides to the best it can, not perfect, but above normal would be good.
HOWEVER, Indeed it is understandable why many, espically Wanda Fans don't want that book and makes sense cause we don't trust Marvel to do it justice and many feel it is time to move forward cause it never seems to work out.
No Fandom wants more pain or contested dialogue for any characters between them, so until then I side with not doing it until Marvel puts on Big-Boy pants and proves they are serious and that be allot of proving the have to do and I don't know how they do it. To Give Confidence in Us, Marvel has to show they are Serious at the very least as a starting point and still they need to work to earn that respect.
So I get it and Hope for the Better in the Future Despite these differences, but it is always good to find common ground too.
