I have 60 barb and 60 demon hunter, 59 wizard and few other lowbies...
I was farming inferno monster power 5 solo on my barbarian all the way thru to killing diablo...so got bored. Didint see how just making mobs harder to kill was any real challenge. Played some hardcore with mates...but still quickly got bored.
I will prolly just get this DLC tho so i have complete set, was always a diablo fan....and at least enjoy a bit of a new story line...maybe get some nice new gear... then pack game away again lol
