The new MG code/behavior is much more realistic than the way it was before. I for one is really happy they changed it to what we have today (it was the same way back in CMx1 when they moved from CMBO to CMBB).
You can’t compare a paper/report with casualties rates with what happens in the game, it’s based on the tactics that are employed and results will reflect that.
The last part of you post is just a rant with no connection to reality. If someone has unrealistic expectations its you.
