Yes, I agree
In that it is comforting to know that if killing a favourite character won't block Bendis from telling a good story, that's fine. But, considering that comics tend to use a lot of 'shock' deaths, and various rebirths, it loses it's poignancy after a while. It's just best working with the characters that you have. Also, Luke is the only visible person of colour (ie- non white- apart from Danielle) on New Avengers. If he goes, the team will just be lily white, with erm... three blondes to boot.
