It still has a few minor flaws but overall is now decent.
There is just a little problem. Alsmost no one i knew from the release is playing anymore and i understand why. I didn't bought the addon, a friend of mine gave it to me for free (he also disliked the idea of playing solo, thats why)
So yeah, it makes fun but starting the game feels like...

I don't like the idea of joining another community just for D3. IDEAL is all i need.

If there's anyone still playing, feel free to add me or post your battletag:

And yes, you can still play with people who don't have the addon yet (so we could do some classic runs) but you won't have access to the new content (new char, act, gamemode, some items, etc)
