you are free to delete your own youth camp, what's the problem?
new championship u21? we already have one u21 championship.
extra promotions for tokens don't affect anything, there are a total of 7 players to be promoted FROM the academy, no matter how many players you promote TO the academy. you can spend 400 tokens every season, you still won't be able to get more than 7 players. it's true, they might be a little bit better than the original 7/8, but not by much. if you're lucky, you get good players from the original ones, if you're not, you'll get worse players for tokens than the original ones.
