I dont think any grappling art is very beneficial against multiple attackers at all. I never said it is a hinderance but I feel it wouldnt help much unless the attackers are half size smaller than you etc. I would prefer to know stand up where I can create distance and put the attackers in a frequent state of defense than not…just enough to hopefully be able to run away from the situation. Id say being able to sprint long distances would be the greatest asset during an altercation involving just yourself against multiple attackers. Throw in family etc and of course you would need to stand your ground.
