C'mon, this thing with CUP is ridiculous
I was lv 2 played lv3 Cup
lv 3 played lv 5 Cup
lv4 played lv7 Cup (with no chance ofc.)
next year what ? lv5 vs lv9 ???
You say that the teams are about the same level even if they are in different levels but when CUP begins in the first day of the season, all the managers start buying 4* and 5* players for the new season.
If a manager lv7 team buy an old cheap player 5*, he would be 8* for me
So ...
My suggestion is when the Cup starting in the new season, a manager must use only the started team. If he wants, he can sell some players and buy new but only for L and CH.L.
