Alright ladies and gents, here is my latest genius idea, which I hope isn't already in effect:
Your fighter's morale is tied to the gym in terms of the way they train and the cleanliness of the gym. This is a negative relationship. Why not consider a positive relationship as well, whereby the 'see gym champs' link now becomes worth something and give a relationship between champs in the gym and the morale of those training in the same gym. Or limit it to those who spar in the same session as them, whatever. Gyms currently promote themselves based off the pedigree of their trainers and top fighters, and you get to do the whole "Oh, Blah McBlah trains at my gym", so why not here too?
