Well, the "best" alliance in my opinion would be The_Just from ss38. However for me it isn't neccessarily because of their fighting nor their 'dominance'. You see when ss38 started about a year ago, I believe (and i could be wrong) That The_Just were at the bottom end of the Top 10, if that and basically nobody knew who they were. Anyway throughout the year, they have managed to use diplomacy in a very strategic way to eliminate any threats one by one with the help of their (and forgive me for saying, even though its no longer) coalition And they've risen to the top recruiting many great fighters along the way and really the only way i can see them falling is either from internal problems, or their allies turning on them haha (Or a b0t sweep HAHA kidding.)
