Any chance of no alliance limit in the future? Honestly this game has been pretty fun so far and I reached top 49 by myself without an alliance on my first or second try but with so many sub alliances there really isn't a point to anything other than solo or 8 man or more. Because no matter the alliance limit, there are going to be quite a few sub alliances to make up for it.
There will never be a world with no alliance limit, of that I am practically certain.
Not a serious world at least. I will say when you become one of the top players in the game though fighting those empires as I like to call them provides some challenge for you since 1v1 fights you just steamroll others.
