Who is in control then? The next biggest alliance has 98 cities, a whole 333 less than PE. You are talking about the 381 cities as if they are whole and all eager to strike back. They aren't. All these alliances added up may come close to PE's total (bear in mind PE still has majority), what is the use in that if it is all divided. All the other cities are divided so much it is clear that no single alliance would pose a challenge; therefore PE are in control unless all the 381 cities combine into a single alliance.I am sure I had some cities in O46...let me check.... nope, still there.
PE has 431 cities in O46 (most of them inherited from PK), but between the other alliances they have 381 and counting. I wouldn't call that control...
Don't get me wrong, I find PE is a great alliance, with above average stats, but there are smaller alliances out there doing a much better job than PE.
EDIT: KOB beat me to it I guess..
