After 4 years of playing this game, day by day and after more than 150 seasons with 3 different teams, I'll say this:
1. Trainings are boring and annoying, and take too much time... At least 3 trainings a day (in my case 9), if you are still in all 3 competitions... We all play Top Eleven 'cause of games, not trainings...
2. We should be allowed to do trainings for bonuses for next day, after the last game, at the evening, instead of doing it in the morning, when everyone is busy and in hurry at work or elsewhere...
3. Trainings should be PASSIVE... Active trainings should be there only for managers who want to build up a player or squad quickly... All condition that goes over 99%, when it's rest time, every 3 hours, should be automatically converted to attributes, depending of chosen training attached to the player... If a player is at 96% condition before the rest, 3% should be added to make 99% and 3% should be converted to attributes...
