I had quit playing about a month after the game came out, was still riddled with problems. I gave it alot of chances because I LOVE the mechanics and gameplay, but was just overwhelmed with the bugs and issues.
I can't remember any specific bugs or issues that would warrant someone to stop playing...unless you were hardcore only player. Damage spikes could of killed the game for early adopters of hardcore.
What specifically caused you to quit or did you just hop on that hate bandwagon?
My blacksmith is maxed out at 10, though. Does the cap raise in MP1-10?
And inferno is pretty easy for me right now.
Nope level 10 is the highest. Now you just have to buy or find the plans from the mini bosses. The armor plans sell for 1.8 million right now so farming those might be rather viable.
