Our faction tags are not showing on any facet outside of Felucca, but we have faction fights in Malas, Ilshenar and Tokuno as well. On Siege, faction fights can break out anywhere at any time. The absence of a faction tag becomes a problem when someone attacks or is under attack by a blue that happens to be in the same faction. The tag isn't there when that player approaches to give us a heads up and as you know, killing someone in your same faction results in the loss of kill points. We'd like to see this fixed in an upcoming publish.
