I absolutely do not understand how the mission rating is drawn up.
On a low MMR (22) I get more points (8.0-9.4), but on a high MMR (41) - 6.0-8.0. Also, the gold reward is different for 200 coins ... where is the logic?

if the difficulty weak influence on the overall rating
remove it completely from the calculation of the rating  and make a multiplier reward for the difficulty.

I also dont understand , MMR is a joke. Theres no benefit for having it higher than a lot more dificulty and a headache.
