In most senses NO, we no longer do sets/forms
The only thing we still do are the "chi kung" things (in Lama, in Cantonese, we have Lihn Gung, Heih Gung and Noi Gung). Basicly these are yoga like exercises designed to teach flexibility, strength, balance, etc
I am sure you know a LOT of MMA people do Yoga and variations.
In fact, I think that one of the problems with the "tradtiional" way of forms is that the forms have three elements
1) fighting technique
2) yogic like practice
3) performance
Yet today people don't know which is which and get them all confused
We do a lot of things to develop the skills
1. shadow boxing
2. partner drilling
3. equipment work
4. partial sparring
5. full sparring
I also developed a criteria, a protocol to see what "works" and what doesn't
Not just in the clinch. You know, the funny thing, really, is that people from my actual tradition clearly see us applying the Lion's Roar technique in our fights and teachings (for example David Chin, David Rogers, etc)
And people who know boxing and Muay Thai see we are not doing those things
Our hand strikes, our angles, our fighting strategy is completely different than boxing and frequently different from Muay Thai
Partially, see above.
Our punches tend to be longer range than traditional boxing. We use a different energy ("ging"). We throw them at different angles, and with different footwork.
HOWEVER, I believe that the other hand MUST protect the face/jaw/chin so you will NOT see the "flailing"
