So the intended design is a gank followed by a steamroll.
That's entirely up to the players.
In practice, what I have seen on the 3 incarnations of the War Island I have played on is a lot of back-and-forth. There's some 1v1v1, some 2v1, some 1v2, alliances of the moment, sudden betrayals, and all kinds of fun stuff.
If you don't want to play there, that's fine, Kai. In fact, you don't even need to play the game, if none of it is actually fun for you.
Meanwhile, the rest of us will be having a blast playing on the new, 3-realm, estate-ful War Island.
