Most notably on the powerplay, the 1st unit tends to get way more ice time than the 2nd, even with the percentages set to 51/49. Very often they're getting over 75% and sometimes 90%+. Of course, this leads to my top players getting massive ice time in some games, leaving them tired.
It is noticeable on the PK too, but not nearly as much, I assume due to having 3 units vs 2.
