3.8 now with only 13 ratings. Give it time, it will rise above 4.0. The exact same happened with my Medieval Map. Some maps are overrated and some underrated.
I'm thinking of making a new version of the map with a few small changes: bonuses 'Kingdom of Gillant' and 'Kingdom of Taratus' will be split is smaller bonuses so the map will be more suited for automatic distribution games.
Also, can someone link me to a 3v3 game played on this map? I'm trying to find some good field-tested templates so I can add this map to CSL (I can also run some tests on templates if necessary).
