I don't like talking much. I'm online checking forums every day, but don't expect me to post often.
As for your status of remaining undefeated, this league is simply not very competitive. If you want to see a competitive league, then check out Season 22 of V.54. Impressive stats for D-5 teams.
Technically, you should be happy about this. The key to being in a noncompetitive league is to enjoy the attendance and income boosts from winning often, yet not winning often enough to promote, because you want to expand your arena to around 8k to 10k seats first. Only then you make your move and go for promotion.
