I wanted to know which clan had the most members so I counted, this is my list by number and then alphabetical order. I only counted fairly large clans. I count feeder clans with overall clans if they are in the same thread.
Triarii: 125
Defiant:78
MoM: 78
Titan: 77
Sparta: 62
Attrition: 60
DD: 56
501st: 53
Krieg:48
Imperium: 33
Thunderstorm:29
Tell me if there are any problems with the list.
