I know all that im just saying it kind of sucks playing the game with out all the bells and whistles that come with it. Rubber gaurd, head kicks and flying knees in muay thai, Throws, Slams. Just doesnt seem right not to up grade your level unless your just trying to pad the hell out of your attributes.
That's why it would be stupid not to do the camps.
Besides the extra strikes/subs/transitions you also get stat bonuses depending on what your style is.
For instance BJJ gets grappling offense/defense and sub offense/defense bonuses.
