I would love an option to turn off other "PC" or other "players" entirely.

(Meaning not being able to see their name, their character, nothing, like they arent even there.)

When doing story quests, especially when a new expansion, or even some patch content is released, hoards of players crowd the NPC, this isnt an "issue" as much of a "eye sore."

So being able to toggle seeing other players/PC's on or off would be a very nice touch.
