my initial thoughts:
1 Massive Rhinoceros Army - Clearly a MRA, like it says on the tin. I think this alliance was mainly for the lulz.
2 Permanent Ban- One of the leading candidates for best alliance on the server. I think we'll see the best of these guys once they've trimmed the fat.
3 Black Bullets- They state 'recruitment is open' and that they 'welcome any player who wants to join'. Bit of a MRA?
4 Last Fallen Nation- Good average points, #2 in O55. They don't state their conditions for membership, but they look decent.
5 Balkan Express- Another one of Slobo's ventures. Will most likely fail.
6 Roman Republic- Unimpressive name, unimpressive alliance. They recruit everywhere.
7 Protogenoi- Decent average, but I don't know how recruitment is closed this early on.
8 Rage I- I'm gonna say the dreaded M abbreviation.. yes, MRA.
9 Scorpio Rising- Pretty poor average, pretty poor profile, pretty poor alliance.
10 Pantheon- Fair few members scattered around 55, not really sure about them though.
11 Memento Mori- Look like a decent alliance so far. Be interesting to see where they go.
12 The Phalanx of Spartans, Uninspirational name. In PB's territory. Don't see them here for long.
