the cash price should help to adjust to the higher play in the division.
if you win div 1, you get the right to participate in the B3(which will give you a very small fincial boost, i believe around 100-150k in average), and higher visitor income then your opponents. I think thats enough, especially because winning div I is a very big achievement at least for me, and motivates me enough to reach it even when i lose money through it.
