I know this probably isn't the answer that you're looking for, but honestly, just try something out yourself. I don't know when you last played, but the game is better than it was from the get-go. Better mobs, better control of difficulty, (slightly) better itemization (and more to come), and balanced/tweaked skills and passives + all the other things that I haven't mentioned.
My suggestion is to just start a brand new character and play the game the way it is now from the start. From the looks of it, you have no Monk and a level 1 Wizard, so you could start with either of those or jump into Hardcore. This will just help you get a fresher outlook on the game, and I've recently done the same. Next, you can try self find, which is where you refuse to purchase any items from the AH and rely solely on drops and merchants (buying directly from a player in your game is alright I think?).
However, if you want to continue playing your Barbarian and don't like the idea of Hardcore, self find, or starting a new hero, most people are farming Act 3 Inferno. You can start there.
no, no, thank you very much for the input. It's Interesting. I pretty much always wanted to self find, i dislike the AH. it has it's uses but the reward for finding your own gear is great. wasn't like that back then,
I played for about 3 hours last night and there is indeed a HUGE difference. I found 2 pieces of gear that I actually could use and one was a legendary shoulders that were quite a big upgrade. I'm glad i gave the game another shot as it really seems viable to actually progress at this point...
now when should I start switching on MP......
