I'd agree that there's a vacuum of options at upper levels. Since I first wrote this class several years ago, I've had more opportunity to play and run games in the 10th-16th level range, and I think that while the monk remix will remain combat-effective at those levels, it starts to fall behind in terms of its ability to impact the game world in non-combat situations. I think some support with powerful, level-appropriate feats could fill that gap, especially if they exploit its epic skill-check capabilities. Not really feelin' any good ideas yet, though. Anyone have suggestions?
