Whatever happened to the DF-crew handing out keys? There's been no updates about that at all.
Don't know but you can apply for closed beta on the PoE site.
Have been playing the ranger and so far this game seems really well put-together. A little easy, but then I'm only into the first tiny part of it, and I guess D2 was also easy right up until the first Duriel battle. Mostly just round up huge packs to kill or more often just run through ignoring mobs and looting stuff.
If diablo doesn't do it for me I can easily imagine myself coming back to this.
