Player rating for online battles on full maps.

I didn't understand it back then – if an automated system can maintain the ranking, why hasn't this automated system been doing it yet? Let it use at least some formula.

I raised this issue with the Creator in January 2015, but at that time, he refused.
Now, permission has been granted to use an automated system. In order for it to work, I sent the Creator information about the report format, lists of factions, templates, and heroes. All that remains is to decide on the ranking formula. After that, everything can be put into action.
However, this has already been discussed in this thread, including information about the automated system from the Creator.
It feels like they haven't read the entire thread :D
