If you quickly skimmed through it which it appears so, I did state that
"Player tags should be invisible unless the player is seen, thus unable to directly know where someone is through walls." ,
only because people who kill anyone or attempt to just follow nametags through walls/blocks. Another addon if I may could be though it would be difficult to code, to raiders perspective(enemy faction), the defending faction nametags are disabled, allowing weaker players to hide and not be harassed as easily and allowing the defending faction to ambush the enemy within their own territory. Making it somewhat understandable since not every raiding nation knows the land of the other faction.
