Personally, I don't want much done with the Blood Angels Codex. It works very, very well, it just needs a few tweaks here and there (I still don't understand the "free" Rhino for Assault Squads without jump packs, the points really don't make sense, especially for a full-size squad).
I would much rather have the last two Codexes toned-down. If the game really must continue that way, Blood Angels may as well be given the "updates" such as insane Storm Shields and free stuff. I'd feel guilty about using Blood Angels, though, until every other Codex in the game was updated to be on par with them.
