I played the PC version at release, and I have to say I'm enjoying the PS4 version much, much more overall. PC release didn't really grab me, and while it had a lot to do with the auction houses, despite the removal of that element I still don't think I would go back to PC.
(That said, I do really hope they bring Seasons to the PS4.)
I've pretty much given up on softcore, which is weird because I always avoided hardcore in D1 and D2. My first HC, Distraction the demon hunter, died to Maltheal at lvl 49. I hadn't played the expansion yet and didn't know what to expect. I'm still not 100% sure what killed me, but I suspect I stood in the bad or got hit by an explosion or something.
HC #2, Hubris the crusader, is now paragon lvl 40 and climbing. Shield bash all the things!
HC #3, Impatience the wizard, lvl 47, scrubbed the floor with Maltheal last night. Revenge is sweet.
