Not to stray much from topic, Dab; but don't you find it interesting that a Guard base would not supply their factions with the highest level items, ie. lvl 10 shields? I believe this is true for all the guard systems.
It seems rather un-RP, and a bit embarrasing, to have to traipse off to enemy or zoner territory to pick up items that everyone requires eventually.
My reccy would be to make the upgrade on all guard bases, rather than as a Faction-specific upgrade.
