The Union
Most everyone is completely active, and if not, they can bring in somebody from the Union 2. They have a good, smart leader in Tyler Boyd, and a high city count. They seem to be at war with The Silence, and they seem to be winning. In my opinion, the most important stat is that they conquered 49 cities, and have lost one. 3rd in ABP.
2. Rising Shadows
Everyone is completely active, until you get down to half of the bottom 12. The leadership appears to be smart. A lower city to player ratio than The Union, but they have conquered 41 times and lost once. ABP seem to favor them, and they seem to be in top shape.
3. Wolfknives
A much smaller alliance player-wise, and they are so much smaller than The Union and Rising Shadows that they actually have a lower average. They make up for that in ABP. I can't tell much about their leadership. They are an incredibly active alliance. Their city to player ratio is only just over 2:1, but they have conquered 31, and lost none. Are pacted with The Silence and Not Alone against Wolfknives.
4. The Syndicate
A very active alliance. I can't even tell who the leader is. While they've only lost once, they've only conquered 16.
5. ALL IN
Very active. About a 3:2 ratio of cities to players, and a ratio of conquests to losses a slim 9:4. However, a good, informational profile and a good leader in Joseph Nieves.
6. Oceanus
Oceanus is active. Who is their leader and who should I contact? City to player almost at 11:7, and conquests to losses only 8:0.
7. Night Warriors
Active. Low quality, but active. A bad 11:8 ratio of city to player, and 5:3 conquered to lost. Not a bad profile, though.
8. Blood Ravens
A semi-informative profile. Mostly active. About a 5:3 city to player rate. 10:0 conquered to lost ratio.
9. Nazgul Elite
Very active. A 4:3 city to player member, and a 5:2 conquered to lost ratio. It has an informative profile.
10. Spartacus
This alliance is active. A bad 4:3 city to player ratio, and 10:6 conquered to lost ratio. Not a great profile.
11. Sons of Liberty
Really active. A city to player ratio of 4:3, and an impressive 11:2 ratio of conquered to lost. A rather uninformative profile.
12. The Union 2
An impressive alliance, even if it didn't have its big brother. Good profile. Active, and a nice 13:1 conquered to lost ratio. A rather unimpressive 4:3 ratio of city to player.
