that actually doesnt make sense to me
if i go pick a fight with mike tyson, there isnt a 50/50 chance i'll win, theres a 99.99/.01 chance that i will LOSE. the only way i would win is by throwing dirt in his eyes, kicking him in the balls, punching his kidneys with all my might, and then running away before he can throw a punch and pretending like i won. luck is involved, but it isnt primary!!
i'm thinking a knockout factor could be included to make fighting with your fists a plausible battle strategy. it gives the people who beat you less experience, you would lose less exp for fighting someone and losing, but you actually have a shot at winning. something of that nature
