Just for the record, I am not playing this in the minmax way some people do with specific "builds" and powerleveling, I am doing my best to just take it slow and enjoy seeing some of the characters I remember from way back again .
That can get you all the way to Inferno... but then there's no way around min/maxing, and you need to either be extremely persistent farming the same chapter over and over, or be extremely lucky to get decent drops, or... spend money on the RMAH.
Apart from the initial server problems, D3 has been a pretty enjoyable experience. It's not as gritty as Diablo 1, it's simpler than Diablo 2, but... it's decent enough and it's pretty
. The best thing about it has been progressing with a group of friends while chatting on Skype.
The inferno skill level is frustrating, though. You basically only have one viable spec per character class, and everything is so extremely gear dependent - it matters a lot more than skills. Combine that with the frustratingly low decent-item drop rate because Blizzard wants you to spend money on the RMAH, and well - not sure if I'm going to fully complete the game.
