Megarandom should be more fair

Two games in row. In one, my opponent was Mongols, the map was full of deer and boars. Easy fast castle with few walls and I'm dead. Second game, my opponent is Tatars, the map is full of hills and literally 50 sheep.

I know it is impossible to balance map script considering sometimes we are missing rez for one player, but still, it benefiting only one player is not fair. Megarandoms turn into civ picker, Mongol heaven more often than not.
