The console versions don't get content updates like the PC version.
And the difficulty was scaled waaaaaay back.
Filthy console scrubs.
That being said I own RoS on both PC and console.
I wouldn't have got it on Consoles, but my friends got it so I figured we'd all enjoy it together. Nah I got left in the dust again. I should've just gotten Reaper of Souls on PC. Ah well.
