remember isn't only a question of belt.The belt limit is just a good way for don't let post here lot of newbie like in evo-alpha-bncy forum.Only thing real needed are skills,and judo isn't the best mod for gain it(btw even judo can help..i learned how to comeback from that mod)
True it is good to learn saving yourself without certain limbs, and coming to continue fights.
The only f*ckd up thing about judo is the first turn ( allways 50% 50% ) and allmost "all people that play it" show real lack of creativity with their openers, so it gets boring seeing thesame 4 openers allways.
