Yesterday, when this patch came out, I tried to play to see if there were any noticeable changes... but the lobby was empty for custom games. I thought the patch had broken the game... but a few games showed up just minutes later (was strange to see an empty lobby).
During the time between not seeing any games, I was on the website and seen information for the new Demigods. I thought that this was the patch that was adding them. I got all excited
Well, when I did join a game and start playing again yesterday, I seen no new Demi's were added ;-/
Oh well, maybe next patch, eh? At least we have some info on them.
