Have to the new patch really has made the game feel quite fun again ! Loving the changes they have made to the difficulties, that was major thing I hated with pre 2.0. I decided to start a Wizard up rather than jump on my "main" DH.
Leveling a new character seems much more fun, you actually get loot which is useful which is much nicer than having to rely on the AH. Started playing as Hard while leveling my Wizard, but I then changed it to Expert it auto levels or something (22). Some elite mobs are a bit tricky and deffo makes you more aware and have to play well rather than just facerolling things which I find very satisfying personally. I'm about halfway through act 1 and my Wizard is at level 23

If it carries on at this rate I imagine being at level 60 before Diablo or maybe just after.
Overall in my opinion this is how Diablo should have been on release.
