Someone has played mots 4 times in a row and his valuations were the same everytime. This thing must be changed or, like you say, next year we'll see mots in nearly every game of the regular season
The right thing according to me is to get rid of this quite stupid enthusiasm thingy. It has nothing to do with reality (especially in the playoffs) and is a very clumpsy tactical tool (especilly on the playoffs).
It does not work that good in Hattrick either (from where it is inherited), but it suites the playoff system very bad, making everything a little bit too much of a lottery. I actually think that the system could be thrown away withou replacing it with anything new imidiately. On the long run the real tactical options (game tactics) can be improved. The only reason why they chosen to inherit the system is probably that it is so easy to implement..
By improving the way game shape woks this could replace the enthusiasm thingy in the long run. It should be harder to get your players into perfect shape, and it should depend more on how much (or little) you play them during the season.
Another thing I would likewould be the possibility to doble team.
