I dont know, I still think the ideas are coming from him, and if hated how the comics were coming out he'd change them.
The problem with the comics, I think, is nothing stopping him. He has no budget and access to every character so nothing is holding him back, and creativity works well with restrictions not complete open control, there has to be some parameters in place.
He's mentioned stories for Buffy they couldn't do cuz of budget, and I'm glad they did have a budget cuz without it we'd have Mecha-Dawn and Willow flying about - and that is not the buffy we had on TV.
Same with the actor restrictions, as nice as that Tara returning from the dead in season 7 would have been, I'm glad Amber didn't agree to it, I think it would have been a total jump the shark moment.
Maybe the season 9 abortion storyline would have been cut by the network, which would have been so much better.
I wish they'd apply the same restrictions they had in the show to the comics, the verse has been defined by those restrictions through 12 seasons of Buffy and Angel, and they've thrown all that out just cuz they can, when Mecha-Dawn and flying people dont fit in with the show - but I think all of that is coming from Joss, he talks about stuff like that in interviews, the difference is now he can do it.
