Seems to be that it went online today. Cool Hero videos and very different gameplay type. Not only a DOTA mode as the adventure mode looks more like a mode where you raid a dungeon with a team.
Wonder which game you have to pay this on alaplaya. I play S4 league and yes the new rental system is not good for older users with perm items but still far away from the situation you described.
Lag is bad when you play with people from the middle of nowhere. More than good when I play with people on the same continent. It is a Peer to Peer game. Still have much bigger issues with other games.
