I would like to see Guild involvement in the PVE World.
Such as ( lets use the hinterlands as example )
When there is a town event and players or guild members take back or rescue a town. 1. Let there be a guild sign on the world map, banners in town ect..
2. let the town be fortifiable like WVW. On A small scale .
3. In the case where guild members are not present let the fortifications decay overtime.
4. all towns represented by a guild be able to be reset by a massive instance by Centars or whatever the general population of Mobs are in the zone.
5. Once town is rest it can be represented by another guild.
I think this type of PVE experience would bring a guild world environment to PVE.
