True, I don't have 15 on matchday, but had it twice after a win this season.
Ok, so far I can see that enthusiasm is very important and can win you some games in very unfavorable matchups, might come handy in the cup, after i stop facing bots
What's the point of enthusiasm going up to 15 if it's more or less impossible to have it up there for a matchday tho?
If you consider the alternative, it may make more sense.
Let's say that 12 is the maximum game-day enthusiasm. Let's also say that the levels from 13 to 15 are removed because you can't have those on gameday. What happens if you TIE at 12? You end up with the same enthusiasm you'd have with a normal at 12.
