Thought of this earlier and wanted to see what the forums thought. So obviously the two primary issues with the Monk of Many Styles archetype is that it is extremely dippable and an awful type of Monk to take to level 20; everyone likes getting a feat level-locked to level 10 down to level 2 and a Monk without Flurry of Blows is likely never to hit anything. I think with two simple fixes these issues can be gotten rid of quite easily:
1) Change the Style Bonus Feats so that you can only take feats for which you qualify for the Monk Level prerequisite. Simple enough and has certainly been suggested before.
2) Add this new ability:
Stylistic Training
At 3rd level, the Monk's many different forms of attack make it difficult to predict or dodge his strikes. For every style the Monk has active with his Fuse Style class feature, he receives a +2 to attack. This ability replaces Maneuver Training.
And with Stylistic Training, the MoMS can compete just fine with full BAB classes on to-hit. So now we have a MoMS that is not super-dippable and is totally playable as a single class.
This makes the archetype so much worse, IMO, since it takes away it greatest strength: Ignoring a lot of the garbage Feats in the chain for better ones (like Snake Sidewind).
Though doing something along the lines of allowing you to ignore FEAT prerequisites but not LEVEL prerequisites might fix the dip problem a bit, and replacing that with something a bit heftier than (an admittedly significant) bonus to-hit. Which is, ironically, VERY dippable as you have it, since you take 3 levels of this class, for an automatic free, unlimited +4 to-hit as a Swift or Free action.
You can still ignore the other prerequisites for feats, just not the Monk level. So you could actually take Snake Fang at level 2 because it has no Monk level requirement but Pummeling Charge would be locked to your 10th level bonus feat because it has a Monk level 8 prereq.
