I also tanked a lot in the last year, since association gets more and more difficult to me, but it gets annoying and boring to me. I'd prefer to just play my season.
Other games have season objectives, why not implementing them in TE? You have a minimum position to reach, or a particular phase in the cup considering the quality of your team or the money invested. If you do not reach them you get some kind of penalty.
Vacation mode has been suggested many times too, I don't know why it takes so much time to implement it :-/
