I don't see any issue with the changes to morale. My team's morale has never been so high and so stable... but then I've never really bothered with it as it didn't seem to affect anything (and still probably only has a very small effect).
If I win my morale usually stays at Very Good, with a few players on Superb. Every now and then they drop down to Good, but they come back up without using blue packs.
I appreciate it might be different if I wasn't in a fairly easy league and winning almost all games.
No ofcourse not!!!!
But Im leading in the League , lost only my first match. ... and won all in the cup and the CL and my morale went from good in the start of the season to almost all players, the starting 11 , to superb...
I did not spent any morale booster this season unlike the season before those one every day I spent like 6 boosters just to keep morale on good
