| I really like the new combat challenges. I like your reasoning behind making it only 2-3 successes. I also like how beating the challenge provides an advantage rather than bonus XP.
The Follow the Leader and Shifting Primary Skills also seem like really interesting, but simple, ways for the DM to tweak the flavor of various challenges.
I'm not too keen on the new player options. I don't see the necessity of Brazen Action, and I think it would make many combat challenges finish quickly. I think giving up both move actions to get two checks in a single round should be enough for most people. I don't know though, maybe this is exactly the sort of option people want. I do like the simplicity of it, and it may encourage teamwork to protect the skill-user.
I don't like Unburdened at all. The armor check penalty is a major balancing factor on many armors, at least for guys like Rangers and Paladins who's best armor has a check penalty. I don't think a healing surge is an adequate price to pay (my group, at least, never seems to run out of them), and the check penalty is only a -1 or -2 so its presence shouldn't make the challenge unbeatable. I would ditch this rule.
