i've just got promoted from div 4 to div 3 but i was in a bot league. so next season i was planning to just use this season to get money to improve my arena. however i could also use this money to buy better players because of the chance i could get an easy league i could do well. so what should i do, buy better players or to build a better arena to increase my income and have more of a chance of getting religated to then hopefully get promoted again?
