I love the idea of the build (except I wouldn't normally touch Shintao Monk till they fix it), but I don't particularly like the feat progression, as the first two feats aren't needed till the very end of the build. They're the pre's for Shintao Monk I, which can't be realized till level 19. Also, two of the best mid-level feats, Improved Critical and Power Attack, are pushed back to higher levels where they frequently get dropped (MinII greensteel makes IC somewhat redundant, power attack turned off for high level content, not needed for low level content due to power of weaponry). Accordingly, I revised the progression for my character to:
Level 1, Human Bonus Feat: Oversized Two Weapon fighting
Level 1, Rogue: Two-Weapon Fighting
Level 2, Monk Bonus Feat: Toughness
Level 3, Paladin: Weapon Focus: Slashing (Whirling Steel Strike Prerequisite)
Level 4, Monk Bonus Feat: Power Attack
Level 5, Monk: Path of Harmonious Balance
Level 6, Paladin: Whirling Steel Strike
Level 7, Paladin:
Level 8, Paladin:
Level 9, Paladin: Improved Two-Weapon Fighting
Level 10, Paladin:
Level 11, Paladin:
Level 12, Paladin: Improved Critical: Slashing
Level 13, Monk:
Level 14, Paladin:
Level 15, Paladin: Greater Two-Weapon Fighting
Level 16, Paladin:
Level 17, Paladin:
Level 18, Monk: Luck of Heroes (for Shintao) or Combat Expertise (if Shintao not fixed by the time I get here, requires +2 INT tome and Wis dropped to 11, INT raised to 11)
Level 19, Monk Bonus Feat: Stunning Fist (for Shintao) or Improved Trip (if shint... blah blah blah)
Level 20, Monk:
After doing some Amrath and Epic content, I'm leery of having characters that can't do some form of crowd control. Every little bit helps. Hence the CE+IT. But you can substitute other stuff in here at that point.
