1) Denial
"Yeah, this is rubbish. I am going to keep refreshing my pages once every few seconds. My invite has already been sent - I just haven't gotten it get. They haven't forgotten about me and everything I've done for Blizzard in the past. Any second now...*click* *click* *click*"
2) Anger
"This is NOT FAIR! Come on Blizzard - how is it that forum trolls, total noobs and brown-nosers can play but I can't! Slap in the face, I tell you! Another rage thread incoming, I tell you what!"
3) Bargaining
"Okay Blizzard - I deserve it more. I can list why: like the time I clicked the chat-gem 5 million times in one weekend, or that time I played WoW for 6 days straight. Let me make another thread and I will tell you all about it. Please give me a Beta....please?"
4) Depression
"Yeah, this sucks. I can't even enjoy other games right now - that is how bummed out I am. We won't see Diablo 3 for ages and I am going to have to be content with watching stream after stream, while drinking this beer until I can imagine that it's me playing."
5) Acceptance
"Beta is out. I didn't get in. I wasn't going to get in. I may get in sometime in the future, but that is unlikely. However, I have lots of games to play, movies to watch and fun IRL stuff to do. At least I can get all of that out of the way before Diablo 3 is released. It will be a while - possibly even mid 2012, but I have plenty to do before then."
