Suggestion:

Klans are marked as either “Competitive” or “Non-competitive.” The competitive Klans are treated as normal in concerns to vanilla raids, and are grouped together as such. The non-competitives act as solos, or with a significant nerf, and are grouped together.

Alternatively, individuals can mark themselves as C or NC for the same reasons, or Klan leaders can mark their clan as such members based on their participation in raids.

The biggest problem I’ve seen with the “Klans in one group, solos in another” idea or “Max 20 to a Klan” is that some people aren’t in Klans for Domination, myself included, and are part of the big Klans for some other reason(mine being obvious).

Just a thought.
