You asked for how it happened, and I gave you the math.So the thing to take away from this is that if you combine numerous features and feats that give certain characters poorly-balanced advantages that Monks can't benefit from, only then does the Barbarian outdamage the Monk. While Raging. Take away a single factor benefitting the Barbarian, and it swings the Monk's way.
And if you want to take away Rage, then you can also remove Flurry of Blows, since they're both a basic class resource. You already granted FoB to the monk, so I gave Rage to the barbarian. If you want to remove Rage (12 damage per round in the example), then you can also remove FoB (11.5 damage per round in the example), and end up in almost exactly the same place.
As for the feats benefiting barbarian, that's an issue with weapons, not classes. A barbarian trying to dual wield axes isn't getting much from the feat system either. Since you wished for the example monk to use unarmed strikes, the limits on unarmed strikes also applied.
Complaining about survey respondents is not a useful avenue of discussion.It cements the fact that the problem isn't Monk Bad, but that common-sense adjustments like better balancing of Weapon Masteries or Polearm Master not giving an infinite-use extra attack will never happen because the most vocal respondents to the surveys will never allow the creators to take away their Optimization.
I agree with the assertion that the monk isn't "bad", though the class is often difficult to use in line with many desired character concepts, similar to the PHB sorcerer and ranger. However your alternate problems are not the counterparts of monk's problems. They are just other things that people might have issues with, and might possibly relate to some of how monk works.
I would suggest that the questions to ask are:
- What are the things that frustrate people playing monk?
- What roadblocks are there in the way of realizing your intended image of your monk?
- Are the perceptions that people have of monks, that lead to disliking the class, real or imagined?
- If they are real, how do we address them?
- If they are imagined, what is causing that disconnect? How can we reduce that friction?
