I tried the crucible as well and really disliked it. Didn't feel good to me at all.to be fair the beta is a very small part of the game. you only have the first story mission (out of 16), pvp, and a strike (there are 6 in the game).
the story isn't anything mind blowing but compared to the first game it's a huge step forward. pvp is actually enjoyable now imo. strikes aren't as good as they used to be. what used to be "patrol" in D1 is now a much larger map with patrols, missions, adventures, lost sectors, public events. way more to do. then of course there are other things like nightfalls, trials, raid.
i'm not trying to convince you because it sounds like you've made your mind up but the beta probably done the game more harm than good. i feel it was aimed more at people who played D1 and not new players.
My post certainly sounded like I'm basing everything on the beta, but after hearing impressions from others, as well as Beast/Bombcast, it doesn't sound like there's much that changes from what I experienced.
