Is it stats? Clan size? Alliance numbers? Coordination? Mass strip funds? Or if you dont think its any of these, Please post your opinion
Stats mean absolutely nothing in a war. With good coordination and teamwork a 2m cs player can take down HLBC.
Activity is the most important thing doesn't matter how big the clan is if there not active they'll lose
Determination. A single 5M CS player can drive a LB clan crazy simply by pinning for weeks, or months. Or years.
