Sad to see no cross platform play. Seems silly not to implement the controller controls and UI into the PC version.

Transmog in D3. Its a neat feature in WoW. I prefer the route of obtaining new and more powerful items that tend to look better. But some people like combine and wear that lv 15 armor. (In WoWs case, some of the random and lower level armor had cool and unique looks)

They are completely changing the UI and controls, which is the main thing a port between console-PC requires. And which many developers fail at doing. As of late we see it more so of the developed for console, port to PC. Not PC->console like D3.
Millions of players, more people to complain. And the majority still are fine and happy.

Would be nice to see more Steam integration into PS3 games come to think of it.
