If I want to be a fan with real war clans. I am sure what clans they are. First would be New Age, Chaos Reborn and WAR. This clans have the great leaders that will not back down no matter the odds. That's my honest answer.
ZAFT = Zodiac Alliance of Freedom and Treaty
When did this guys respect freedom. They are the worst ally hire hit. They are known to KAW pre HTE. If you want to fast track in LB join ZAFT. They are design to fully protect LB players. Only person really follow and respect ZAFT rules was Laoda. You may not like ZAFT but they have great leader like Laoda and b0ring.
YAFI tried to copy ZAFT and failed miserable.
They had a niche that works but their new leaders destroyed it trying to be ZAFT
Fury just leaching on ZAFT current vulnerability of being worried on Apoc rapid growth.
