There will be population caps for Alliances, as noted... https://en-forum.guildwars2.com/discussion/26547/world-restructuring “Our current plans for alliance size are somewhere between 500-1000 members, and we are still considering the technical and match-making ramifications of the number that we settle upon.” https://en-forum.guildwars2.com/discussion/45856/world-restructuring-update-1“Alliance sizeWe are currently leaning toward alliance size being 500. This is technically easier, as we already support groups of this size (guilds), and it gives us more flexibility to make the worlds even.” This..."Yes, we only use play hours in WvW when doing the population calculations.".. is for matchmaking purposes. You missed the point. Alliance number cap has nothing to do with WORLD caps which ARE based on playing hours. A world will not only have people in an alliance it will also include people who are not part of any wvw guild or ally so an Ally cap is irrelevant to the point. So the point is anet will be basing when to cap a world's population based on players playing hours. Meaning there'll be zero balance and worlds will have a completely different amount of players and world caps. When we have a system that will cap a worlds pop to 2k players and another capped at 4k players who play less the system is already broken and unbalanced. So I say again unless there are REAL changes to the issue of balance then anet is just bringing the same unbalance to the new system and thus it has 100% chance to be a failure.
