Fuck IBJJF!
It may be true for now that the top talent goes there, partly because they come from traditional schools, whos teaching, matches the ridiculous rules set.
You have to spend as much time learning the fucking rules as you do learning grappling.
If we ever want to see the grappling sports merge techniques so that the next evolution of grapeling can be born. IBJJF must die.
I urge everyone to boycott their events. If you truly feel you need to go IBJFF because you are at the top level in the world, speak out against them and make things change instead.
