I dont like fast play rewarding very much. Many players prefer TBS because they like unhurried thoughtfull play. If they wanted something more intense they would play RTS. When I was playing Darklords by email, it took me up to an hour to ponder on how to move my units, what to build, what spells to activate etc. And I could think on current in-game situation sometimes during the day. It was a great experience and i'd be happy if Steve made W5 to be something like that. Asynchronous play its named, you enter the game, do some management, press next turn and leave until another session.
