I honestly think that a limit of 1 event per "turn" would be enough, in which case the ability to "buy away" events could be scrapped. At the moment it feels like an overwhelming abount of stuff happening all the time, which has put off some of the gamers in my group from this game.
I look forward to trying out Descent 2nd edition this weekend, I have high hopes that it will be a bit more in depth and cover adventure/character stuff as well as the tactical gaming. I kinda miss that in D&D:WoA.
