I´ve also played beta and what i disliked the MOST of ALL is the following:
1: It shows your DPS instead of Damage. I know that alot of people here thinks that damage and dps is the same thing. The difference is. DPS = Damage Per SECOND. Damage: Your TOTAL damage. So seeing 15 dps makes you think...bah i want to see my damage, this sucks. Either remove "DPS" or add Damage as well or Diablo 3 will fail.
Everyone who doesn´t get in will always rage about it and i feel you and i know where you are comming from with this and i totally agree on the point that only letting NA in is not so balanced or fair. There is a 1-3 order to follow to maximize the profit for Blizzard to go through.
1: ONLY let people in who have experience in beta testing (phase 1)
2: Let both EU and NA stress test the servers (Phase 2)
3: Profit?!? (Phase 3)
