So, no worries.
Worst, worst case scenario Bendis has one of the 05 toss a few Brotherhood of Evil Mutants slurs her way, and everyone hugs it out.
I'm really not worried. :D
Bendis facilitated the return of her kids. He opened the dialogue about her little family, and Billy and Tommy are now refular inhabitants of the Marvel Universe.
All he really did was take her off the map for a little bit. And, I don't think he intended foe her to be gone so long. Heinberg is the one to blame there, I believe. Wanda's return was seeded in the very first volume of Young Avengers. That he took so long to return to the franchise (while refusing to let others pilot his little ship) is not on Bendis.
The massive X-fan hatred of Wanda isn't on Bendis either. That's on the over dramatic X-writers and their dumbass Decimation overkill.
If you want to blame a writer for f*cking with Wanda, talk to Byrne.
