I actually think it makes sense to have multiplayer and single player favor points seperate....
Seriously... are some of you people stupid? If you combine the two you can just noob rush easy difficulty tourny getting favor that way. No skill involved in that, sorry.
Seperating is good. It seperates the good and bad players online, rather than rewarding the players who sink more time into the game but suck. Skilled players would generally have more favor points, but not necessarily more hours played. Good thing.
