Pre-ordered on the first day I could. I also like my ITS mousepad.
Did a run through of the new bets last night with an assassin and had no trouble at all with the combat. I hadn't tried an assassin in the first beta, so I guess I can't compare. Thankfully, my drifter and grifter still got roughed up, so hopefully they didn't tone down the difficulty too much. And, no, I did not hit the "awesome" button.
