Another suggestion, which I insist and I will continue insisting.
In the "About PPM" link you assert literally: "...You can create your own team and make your dream about managing a sporting club come true. Realistic game simulators will test your coaching skills..."
The word key is "realistic". I haven´t played much in the other sports of PPM, but I have clear that handball is not a realistic simulator.
NO TEAM HANDBALL in the real world changes all their players in attack and defense. Any team to do that against a team of similar level and even a little less lost the match in 100% of cases (ok 99%

).
I think that not having sanctioned this somehow, the simulator has been distorted from reality and has caused that right now a large percentage of teams that win their leagues and national teams too, use 6 players to attack and six other different players to defend, because it is clear that they have a clear advantage in training versus those who try to make a balanced team. They just have to train shooting or blocking.
At the end all the teams will follow this strategy, which is not "realistic" simulator and bored.
