OK, I hate to be "that guy" but here we go. The Angels, same as every other chapter with their own book get stuff Codex marines don't. In exchange, we get stuff you don't. That's how it is and how it should be. If everyone gets everything then there should be just one codex and the BA/SW/BT codexes would all be declared obsolete and unusable for official play. They are diferent and that's the whole point of them having thier own books.
Basically what you don't get from the new book (chosen from what's been begged for/debated since October...others not listed left out for lack of begging):
Relic Blades/Storm Shields/wargear variations, new psyker powers, BS 4 Drop Pods, Land Raider upgrades/POTMS changes, new veterans. There's probably a few more that BA players want, but those seem to be the biggies.
What you DO have that we don't:
Faster Rhinos, assault troop choices, better chaplains (that are also more useful), Rites of Battle, Death Company(FREE, RENDING marines...what more can you ask for?), Assault Troops, WS/BS 4 scouts (sure they're elite, but they're WAY better snipers then ours are), Baal Pred, Furioso Dread, DC Dread...
We have different stuff then you and you have different stuff then us...maybe because we're DIFFERENT armies. If we were all meant to be the same army, we'd have one big book with everything in it and what would be the point of the diferent codexes? If every army was supposed to be the same there would just be "Codex, 40K" and everyone would have exactly the same army. The differences are what make the varied armies all fun. Sure you're Space Marines, but you don't work like mine and I like it that way. I thought this argument was put to bed months ago and aside from what may be the fastest banned member I've yet to see most people get that. There are armies that DESPERATELY need work (Dark Eldar...Necrons...) and they are getting that work. The Blood angels are in good shape right now, so either play this fluffy and fun army as always or if you want the new stuff so bad, play a standard codex army. Don't expect to get both because then there'd be no point to have your special book at all.
