What purpose would Ian fighting Axel outside of MMA? From what I've seen Axel's obsession with Lena seems to have lessened. I don't think Ian will need to protect any of the girls from him. Unless beating him in MMA is what you mean.
Well first of all it would be fun to have another street fight-esc scene between characters in the game. I think it's 10/10 drama and fun to watch. Watching Ian beat Roberts ass was rather fun IMO, so why not get some more?
Second of all, I'm not sure where you're getting this unanimous thing of his 'obsession with Lena lessening.' As the last interaction between the three of them, outside of the nightclub. Has Axel trying to 'bitch' Ian and push him over while really not seeming to be 'over' Lena. And then Ian and him can also have another 'verbal fight' this time, of Ian daring him to try something when he runs into him with Cindy if you meet certain requirements.
Quite a few signs there pointing to them eventually having a bit of a brawl. And I think the average person will want their MC to win said fight. And put this fucking smug gorilla posing, aryan dreamchild, on his arse.
