The problem with this approach is twofold:I think it would be cool if like Sorcery Incarnate, you have a limited pool resource that you can activate several times a day, only provide several options and flavor it as stances, each of which reduces a specific Di point cost. You can still use Di points in our out of the stance to activate the other abilities, but the one you choose causes the Di point cost to be 0 while the stance is active.
Dragon - 1 minute 0 cost FoB
Cheeta - 1 minute 0 cost SotW
Bear - 1 minute 0 cost PD
1) It is heavily based on eastern martial arts themes, or more accurately a western misinterpretation of them, which is exactly the sort of thing WoTC is trying to avoid by renaming Ki into Discipline points.
2) Even if we are fine with the monk remaining pudgeonholed into being an Eastern Martial Arts user flavor-wise, it still would be difficult to get any two people to agree on which "animals" should be included. Sure, many might agree that Dragon should make the cut, but Cheetah? That's not a recognized martial arts form from pretty much any actual martial arts forms. And even other cats would be disputed. Do you use panther? Tiger? Why not mythical creatures like sabertooth? And why bear and not Owlbear? What about other animals that would logically make sense for some fantasy settings? I.e. should there be a "Hydra Style". If so, what would that entail? And would people consider that offensive because it isn't an "authentic or real" martial art? Etc.
I'm not saying it couldn't be done, I'm just saying it isn't as cut and dry and simple an approach as one might think.
I do all of these houserules as well. It's still not enough. For starters, it doesn't address the big Weapon Mastery elephant in the room. Additionally, it doesn't address the concerns over whether monks will be barred from martial feats (due to losing short swords in the last playtest). It also doesn't address that Stunning Strike is a badly designed feature as it incentivises the monk to blow all of their ki on locking down one creature and then complaining when they can't do anything else. Finally, it also doesn't give monks much in the way of out of combat class features, which the barbarian and fighter are both gaining in this playtest.I already posted the solution: give bonus di = to wis. modifier. Flurry of blows works off the attack action. Patient defence works off the reaction. Step of the wind includes disengage and works off the bonus action. Boom. Monks fixed.
For myself? I'm currently testing letting monks apply weapon masteries to unarmed Strikes using ki (basically they can pick ANY mastery with unarmed attacks) and have given them another feature that lets them spend a ki point to roll a martial arts die and add it to an ability check as a reaction. Just to give them a small perk out of combat and not encourage them to hoard all their points for stunning strike.
