First off, I have to admit that I didn't look too hard to see if this had been answered already, but I did poke around a little and didn't see anything. Also, forgive me if this is the wrong Forum, it seemed best.
The question is in the title. Why must all alliances be sorted out in the public chat? I'm playing a game right now where I allied publicly with another player, to which the other players immediately allied together and beat the tar out of us.
Having to publicly declare your alliance seems to defeat the entire purpose.
