“It’s probably Matt Mercer’s fault.”
1. Subclass abilities that don't compete with base class abilities for Ki
2. Less emphasis on colorful but rarely used abilities at higher levels
3. Damage that scales a bit better at higher levels
4. Some kind of unique "thing" other than Stunning Strike that really plays differently than other classes
There are lots of ways to achieve these things (more Ki, faster scaling martial arts dice, special abilities, bonus feats from a prescribed list, etc.). But those would be my design goals.
For the unique thing, my vote has always been for one or more bonus reactions.
