I was wondering 2 things.
1- If I play with my rival in the playoffs, does it affect fan survey? If so does it reset (I mean FS) before next season?
2- Does your rival change if both of the teams stays in the same division?
1: I think it does. Don't think anything resets. Not sure though.
2: your rival could change. But I
think that if you stay in the same division it is rather unlikely, since rivalry depends on how many times you guys faced off against each other, and also if you win some and loose some. Unless one of you clearly improved, it is likely your win/loss rate against the team will more or less stay the same, which makes it likely you keep your rival.
However, if there is an other team that entered your division, and you played some games against him in previous seasons, or after a while in your own division now, and the results are more 50/50 then your current rival, I think it will change to the new team...
I'm not sure how EXACTLY it works, but yes, rivals can change, even though both stay in the same league.
They are not your friends; they dispise you. I am the only one you can count on. Trust me.
