Not a fan. Not a bad idea, but in my opinion the game as it is designed is not suitable for it and it could cause some issues:
- what Kukoc said
- you won't get anything for well trained staff anyway
- bidding on staff could get more complicated
which could lead to higher prices of specific high profile scarce commodities; difficult evaluation of level, skill and salary; bigger advantage for time spending (aka active) type of managers which is against BB principles
- more things to run vs server issue
I would rather make a different suggestion and suggest that pool of staff, trainers especially could be linked to number of managers total both in quality and quantity to prevent thjem getting more and more expensive with raising numbers of new trams. Current situation makes it harder for new teams to start. I think price of th staff shuld be to some extent constant and only influence by managers behaviour and balance of importance/cost of other things in the game nit just by brute strenght of dull number of managers in the game.
