I think it wil be smaller map.
Something with the new 2 tribes.
I guess same artifact system like old special server -> areas to conquer
I also guess, that also the waterworks will get nerved. Maybe way more expensive or less oasis bonus.
As often told I guess it will be hard to have multis. Maybe just make legal teamwork better -> be able to support allianes you play as team with (even if not the same alliance)
