Currently the Guild permissions allow a rank to be granted the rights to “activate built upgrades”. This is an all or nothing option which is unhelpful to a Guild with broad interests.
Most specifically it would be particularly useful to have a separate permission to “activate Art of War upgrades”.
All upgrades (except perhaps +10% PvP influence) in the Art of War category are specific to WvW and it would be helpful to create a rank for WvW_officer and grant them control of those upgrades without also giving control of any other upgrades which may or may not be of relevance to WvW.
