Just beat Act 1 last boss solo on Inferno. Phew! The enrage on him is ridiculous (if you take too long, the bosses get a special layer of difficulty added onto them), so I had to change my build and lose my nephalem buff. Done for the night, will go back to farming A1 again tomorrow.
And maintenance is done in 15 minutes.
