Many of you have asked about MM chart for 8.6 update. Well below you may see version of 8.6 MM chart for Public Test #2 version (it may change in the live version)
So what have changed? Well, all SPGs received Tank Destroyers MM, which is much tighter. No other changes were performed.
I hope that this information helps.
Later today details on tracking system in 8.6 will be posted.
