The hidden stats make the game interesting and irratating, unfortunatly. I could not tell you how my guy with 4 stars in BJJ got subbed by a guy with 2.5, but it happened. Drove me bonkers, but when you are on the other side of it....That is a great feeling. I try not to take it as a personal affront when someone with WAY better stats challenges me, but you can always hit the deny button. The greatness of it is when you accept and win. The whole "That was bullshit note," makes it worth it.
