I beat him pre nerf, but honestly I think it's much more fun now. It's more, and less, challenging in the right ways. You can now maneuver the map without 2 shots from a dreg blowing out your colon. It's still necessary to use caution and defend yourself but it's not almost impossible. Also you're not being endlessly swarmed with bad guys. There's breathing room to regroup and rearm. Skolas also doesn't one shot you by accident from across the map. Teamwork and coordination are still required but now it's fun challenging, not damn near impossible if everything doesn't go absolutely perfect challenging.
