Okay, here's my opinion, and the opinion of some participants...
I love the ginga in BC32 - the turning front kick is a far easier progression than BC31, where you had the ESK, then followed quickly by another difficult kick (truely, there are participants out there who really struggle with the jump-kick still) - I felt like I had to continually talk them through the moves, rather than being able to use more 'feeling' and motivational cues in the second half. A lot of participants have hated track 4 in BC31.
One of the gyms I work for, their participants HATE the ginga with a passion. The numbers were dropping significantly. For example, a Sat morning class with 30 regular participants, dropped to 10 in the four weeks following the new release - when surveyed, the missing participants stated how much they disliked the Capoeira element in BC, and that the music was becoming boring. On the flip side, I take a class on a Sat morning at another gym who have embraced Capoeira with a passion.
While it may be easy to place blame with the instructors, it's not always the answer to falling numbers. I've started a BC technique class for my participants. It's 30mins, once a month (usually on the first w/end of the month), right before the actual class. I continue to get 15-20 participants coming to that technique class, who then stay and do the class afterwards. They've all told me how it helps them get a better understanding of the moves - and it seems to be working, because they're all doing the ESK at level 2 (or better now).
I know that Les Mills say "Push play and go", but I'm not sure this phrase is entirely relevant any more for the new, complex moves, and the speeds of today's BC.
But, glory me, I love that butt track!!
