It's the age of the players that bothers me the most.
The season is half over and the offer is for 26 - 28 y.o. players that will be 20% worse next season and due to their age will not get better through training. I like the idea but they should at most be 22 y.o./117%+ so that we can get 2 - 4 seasons out of them (including this one). This offer works best for tankers who do not risk the advancement loss in quality.
