i survived in D.4 with 6500 seats, so it's not hard to promote, spend 200k on seats , and float in relegation for a season imo if you understand GS. The bane of most people, including me, is they are either training guys that are at the starting point (18-19) in D.IV, or haven't made good investments on players, either getting one way guys with salaries that are a bit too high for that set, or overspending and dont have it all put together yet.
