I also don't do association for the same reason. In fact, perso I think a season should be 40 days instead of 28, so that some days would be less crowded. Also one reason I don't spend money in this game is because I know it is kinda pointless since 28 days later I will have to rebuild. If it was a longer time between eac rebuild I wouldnt mind as much to buy some tokens. But I guess the engine is set i stone now.
