We have updated the algorithm used for our GuildOx PvE realm ranks at:http://www.guildox.com/go/g.aspx?a=11
The old system simply took a sum of the progress points for each guild on any given server. This had the downside of favoring servers where there were a lot of guilds that raided, not necessarily guilds that progressed.
The new system looks at only guilds with a top world rank, weights them based on how close to number#1 they are and then sums them accordingly. The result is a PvE realm rank list that better reflects servers that features guilds dealing with heroic progression.
Please post any thoughts you have on this.
