Playing against neutral factions will significantly prolong the game. I usually have 3-7 battles a day starting from day 1. And here, there will definitely be challenging battles. This means the game will be continuous and will take 2-3 times longer. Overall, it will be a completely different experience. And there won't be any surprises in the Facebook group. But there's something to the idea, and it would be interesting to organize a tournament like that.
