This looks promising, but I have a few concerns. Kill/Death ratio directly influences the result of skirmishes, but you don't seem to be considering it at all in the "player score" - I strongly believe you should.To create a balanced world population seems like a daunting task. What constitues a good mix for a world population? (more on this below)How to create a good alliance: alliances could possibly have the same problem and the players don't have statistics to rely on to have a good picture of what our alliances lack. As the bare minimum you can consider to expose the amount of hours played, the timezone covered and the kdr for Players and Guilds, but there's a lot more that could be useful (see below)Small guilds and guild cap for alliances: in my WvW guild with about 40 people in the roster, only a few are still playing. If the guild size is not calculated based on active players I would probably have to kick my friends that are not playing, or I should join another WvW guild. Both those options are bad :(Balancing for rolesAny player could have a "profile" accounting for how much of these activities they performed. In some cases, maybe the activity of the whole squad could influence the role for each participant? Note: commanding is tracked separately, so you could have an Assaulter Commander, a Sieger Commander and so on. Assaulter Kills players in enemy territories.Hopefully, you already have the metrics to keep track of this! Sieger Builds and uses offensive siege. Captures enemy "walled" objectives (towers, keeps, castles).Not sure if ANet can already keep track of this: siege building in enemy territorysiege usage that damages enemy objectivesif the objectives are captured by the player's faction before the siege is destroyed or the defense timer expires (if the siege is destroyed or the defense time expire it should be considered a failed attempt)Caretaker Builds and refreshes siege in allied territories. Escorts dolyaks. Claims and applies upgrades to objectives. Probably needs a few metrics added for the defensive siege?Could possibly be exploited by trolls. Defender Kills players in friendly territories.Again, hopefully you already have the metrics for this. Roamer Captures enemy "open" objectives: camps, ruins and shrines. Kills dolyaks.Again, hopefully you already have all the metrics for this. Additional MetricsA few more ideas of stuff I would like tracked. This would apply to Guilds, single Players and even Commanders where it makes sense. Was engaged in a fight, but went off combat before any participant diedHas failed to capture an enemy objectiveHow many times has fired siege X (cannon, arrowcart, mortar, etc...)
