For me the RMAH will be a little cash shop, will see if anything sells, if it does I got a little bit more cash for some beers
Legendary is brown and I got one at lvl 14 yesterday called Mojo, only for Witch Doctors. I have not found one piece of green gear yet, found lots of uniques though, like everyone else.
The darkness of the game is still around, just the graphics make it seem like its not. When I was fighting the final boss in ACT 1
The game still had that theme of death and spookiness.
The log in issue happens with WoW too it will die down soon enough.
