I like the idea of lvl decided by members. Using your example, rating would look like this now:I just think that progress in the game should be counted in somewhere. I thought that was what the most powerful was. Right now a guy that has 400 level 10 chars in his clan has 400x10= 4000 as his clan most power stat. That just doesnt mean much to that clan of 25level 80's who have a rating of 25x80 = 2000. Yet those 80's have all the bosses on farm status.
400 ppl with lvl 10: 10 / 400 = 0,025
25 ppl with lvl 80: 80 / 25 = 3,2
Going back on your progress, the list could look like this:
World - Clan Name - Nr of Members - Rating - Boss Points
Maybe have certain points a boss gives, for example:
King G and Hairy : 0,5 points
Catacomb Bosses: 1 point
Shalmont Bosses: 2 points
Stonevale Bosses: 10 points
Strongest clan should be measured first by bosses killed and secondly by lvl. It should look something like this:
1st place: Arawn - Clan A - 25 - 3,2 - 53
2nd place: Arawn - Clan B - 25 - 3,2 - 20

Also, I don't want to have a "best" clan. I don't like that word. The value of a clan isn't about the overall player level, but about people in it.
