It has been discussed a lot wheather attrition is to hard in this game (and I think the developpers have already stated that they are working on this issue?). However that is only one side of the problem: the other is that harsh weather occurs very frequently. Nothing against a harsh winter or a muddy spring that part is very realistic. But harsh weather
also occurs in the middle of the summer months
. And that strikes me as unbelievable.
Here is a screenshot from a recent campaign which shows should highlight what I mean:
A blizzard in Southern Russia (the screen depicts the region just east of Tzaritsyn) in August?
It might be worthwhile checking the code regulating the weather.
