There will be a massive difference between leagues for a long time and promoted team will suffer a lot. Relegated team will lead Group B season 2.
That is the idea (eventually), that Group A will be stronger than Group B. However the promoted team will not suffer, they will have an influx of Nohhams at the end of the season to make them competitive. Similarly, the team relegated may indeed have a better team but managers will have to risk playing expensive players when the return isn't as high. For example, you may not be able to make a profit on an expensive player, so they'd have to drop the player and the promoted team would have the funds to pick them up.
just imagine bucket 10 players having same baseprice as bucket 2 players
Pretty much!
