... it is also very hard to have to take weeks off to train free throws if you are trying to develope a U21 player. It seems to me like if your player starts out with atrocious free throws, they are stuck with <awful free throws until they are at least 22.
If you want more than 3 FT on a guy, then
train it. The very fact that it's hard to do shows that the choice is an interesting strategic question. And if a strategic question isn't hard, then it's boring. So, You can either train FT, and accept slightly lower main skills, or you can train other stuff and accept slightly lower FT. That's a hard choice to make sometimes. But the hard choices in BB (arena versus buying players, trainees versus veterans, old fart versus young guys, focus on training, or cup, or league wins) are
exactly what make it a great sports GM simulator.
And just because there are some users who would like this change, doesn't mean it's a good one. You could probably get a good fraction of users to agree that training should be 5 times faster, or that TV money should be 10 times higher. That wouldn't make for a better game.
