I'm not sure if this is 100% accurate but it seems closer than the 'Most Powerful' list on the leaderboards. Here is a few of the top 2 or 3 clans in each worlds' 'Average Level of Active Players' that I've calculated using this method, rounded to the nearest whole number, and if it is a bit more precise, the power ratings need a little tweak

Arawn -
Uskoci: ALAP = 111
Badabing: ALAP = 132
Belenus -
Elementals: ALAP = 134
LivingLegends: ALAP = 105
Danu -
Prime: ALAP = 138
OmegaTriad: ALAP = 51
Unbreakable: ALAP = 106 (Omega have a higher Power rating)
Herne -
Defiance: ALAP = 143
HateYouSoMuch: ALAP = 32
Infection: ALAP = 129 (HYSM has a higher power rating

Morrigan -
Avalon: ALAP = 149
MarathDamane: ALAP = 126
Golgatha: ALAP = 90
Sulis -
Retribution: ALAP = 135
Olympian: ALAP = 60
SulisLegends: ALAP = 104 (Again, Olympian has a higher power rating)
And feel free to post the results for your world if I haven't yet

I know the Online Rankings don't mean anything and are just for show etc, but I'm sure most will agree they're fun to look at

Also, the problem with my results is that it does not show balance. A clan with 50 Warriors is less powerful and can't take as many bosses, efficiently atleast, than a clan with 20 Druids, 10 Warriors, 10 Mages, 10Rangers and 10 Rogues.
Enjoy
