I think a change in how earning influence works can bring the GW2 community -- especially Guilds -- closer together; if not "physically" (mentally). Players would be allowed to toggle what they are earning their influence for (whether it be through playing or buying reputation). Two options in the toggle would include WvW (server level) and Guild (across server or region if possible); Guilds would have two separate pools for influence accumulation.
Influence earned for "WvW":
While this is toggled, all influence earned and accumulated only counts towards upgrades from the Art of War WvW section for members of a guild on their specific server. This would keep WvW fair and server restricted as it is now.
Influence earned for "Guild":
Here all influence earned and accumulated only counts towards upgrades from Architecture, Economy, and Politics. Since these have no effect on WvW they would be server wide so all members can feel more connected and not as left out (especially if they are the only ones on their server); everyone would be able to contribute and enjoy rewards.
With not having regional guesting, I think this could be a further step in strengthening communication and involvement of players separated otherwise.
I am not a programmer so obviously do not know the details such an implementation would require. Naively right now I would conclude that such would involve more resources to track; how much, and if it is even feasible, IDK. Since the BLTC is already cross-server/region, I don't see why this revamp of influence and rewards couldn't have a work around somehow.
With the upcoming Guesting, I would like to see a future possibility in right clicking on a person's name with the option to immediately guest on their server (as overflow works now) -- something else that would be nice to do from the Guild roster.
Meandering from my own initial topic, but this thread is basically ways to bring Guilds closer together in recent news of how guesting will end up working.
