Dannyalcatraz said:While What I dislike so much is that the class only models one archetype of the unarmed/light combatants- the aforemention Shaolin master type. Pankration wrestlers? Capoirists? Thai Kickboxers? Savatte masters? Judo practitioners? None of them (and so many more) are truly represented by the class....
2) Broaden the way martial arts work a little. Since some martial arts are aggressive, there would be a high-damage option. A martial art that depends more on throws and holds wouldn't see a standard damage increase, but would instead get BAB bonuses for such maneuvers and enhancement to non-lethal damage. To reflect this, a PC would choose a School of unarmed combat at 1st level, which would include associated feat selections and special abilities
Mechanically, a School would probably be a cafeteria of offerings, with successive choices based on previous decisions... For example, it would be very difficult for a PC who took a "reactive" School to take certain "aggressive" abilities, and vice versa.
3) Monk weapon lists would vary from School to School as well. After all, the weapons used in Karate differ from those of Escrima (short staves) or Capoira (in extreme cases, they can fight with or even in manacles) and so forth.
I don't think its feasbile to offer the breadth of fighting styles that many people seem to want within a single class. Unless, of course, the styles are represented as feats, in which case we're back to letting the fighter be the best possible hand-to-hand combatant just its the best at all other forms of feat-intensive combat styles.
Dannyalcatraz said:Its not as bad as you might imagine- I did something like this in 2Ed. (Admittedly, it was easy considering that HERO 4Ed had a chart in its Ultimate Martial Artist release that allowed conversion of that games' martial arts maneuvers into D&D stats.) Honestly, there are all kinds of other RPG systems that have done this successfully- like GURPS and HERO- and all that need be done is think in a similar fashion.
It would require a little bit more typing on someone's part...but no more than a typical section of new Feats or Spells.
Considerable--but as you say, it's open to a number of classes. It's not all stuffed into the wizard's class description.Dannyalcatraz said:And even though the current design is open to several classes, what amount of text devoted to arcane spells?
Not that much really. The PHBII was notable for finally upping the count of high-end feats.Or to fighting feats that only fighters will ever be able to use?
Or you can design it to be openly compatable from the start by incorporating it into the feat subsystem. I'm not hearing what the basis for objecting to that is.Besides, once you set up the School system mechanic, you have the option of opening it up to other (proabably prestige) classes, or such closely related classes as the Ninja or the Soulknife.
