Which makes me think, the Gym really is useless? I mean if you're an older team or you have tanked some seasons on hardcore then yeah it MAY be worth it, but
1M initial investment + 15k each week for 6 season equals
1M initial investment + 1,35M weekly maintenance for 6 seasons equals
2,35M invested for 8 pops each player in 6 seasons, that's paying 261.1k for each crosstraining pop for your utopian team
Of course if it's 2 players a season you halve the cost to 130.5k each pop, which is still a lot of money
for your greek team
1M initial investment + 15k each week for 4 seasons equals
1M + 900k = 1,9M
1,9M invested for 9 pops equals 211.k for each crosstraining pop in an individual player
105.5k for each crosstraining pop in 2 players
Which to me is still a lot of money just for SB/RB pops...
Question : Why not buy a player with a decent level let's say mediocre in RB or SB and then just spend 8 weeks from 18y to 21y on these skills to achieve the same effect?
With how trainers are nowadays you will still be able to finish this player training until 28y/29y and you'll have an extra 2M+ to invest in many more important things
