I think whole training system is very unfair and unrealistic...If some day developers will change something I would like to see:
1.No training from national games at all.
2.Much less experience from national games (about 1 star after 75 games)
first of all, to compensate for this, the injuries should be removed. i don't want my players to play and get injured for no reward. and spare me the 'be proud for having a player in a national team' line. in case i'm only exposed to the drawbacks, i don't care if my player is in nt or u21, i care if my team wins. if some of my players get injured every season from playing in national teams, at least now i get something out of it.
second of all, if they implement your ideas and there are still injuries, then many users that get extra youth players into academy for G or tokens would stop choosing smaller countries and go only for the 5 or 6 big ones, so their players won't get selected for national teams, unless they are la12-13 monsters. this migration to big countries would lead to the burial of medium and small nations and the creation of only a few super-powers, similar to what happened in youth camps.
1.For equalization of changes in national teams,players should lose progress rate after 22y. (+1 year when compare to current system)
this should happen anyway, because the PR of players has decreased and the academy players are, on average, over 17 y.o.
the 8 players i received at the season reset had an average age of 17,875. that is too high.
if the average would be around 16, it would be ok the way it is now.
2.Daily training should give much greater increase.
3.Match training should give much smaller incrase.
i thought you were going for realism. what happened?
is it realistic to be able to train a player without playing him?
on the contrary, i think the training amount from matches should be a bit higher. but not too high, so it won't discourage the new teams from upgrading the training facilities.
