Oh I agree that the people who say they are "locked out" of content really aren't. The only thing in D1 that I saw a barrier to getting was the adept weapons. Flawless was very difficult and it was the only way to get those guns (and the 5 and 7 win loot to an extent). Personally, I like that I use a gun in PvE and jump to PvP and it behaves and feels exactly the same. Not everyone thinks this way though and I know that. Bungie will do what they feel is best for the game as a whole, they aren't in this to fail.
