It's far from being over.
With your new C you achieve great ratings, and should start getting home wins on a regular basis. Unfortunately, we're natural "opponents" since I'll also have to fight all the way to stay in this division, but trust me : things are not over.
Little mistakes can lead to surprises : Stonestars' TS loss in the Cup allowed me to surprise him tonight. Coach Q's injured players led to his first loss this season. Amenra slightly underestimated KV, ... and so on. Last season I was sure I couldn't promote, but finally here I am. After both favourites lost in the conference finals, much to everyone's surprise ...
I still think that Angels, FTA, you and myself are favourites to go down, but it all depends on so many things ... A new player, injuries, GS, TS management, Cup ties, and so on. So it's over when the last game is played :)
