When players do not move, you can hardly distinguish him is the player or NPC! So far I’ve used two methods:
- Look for a guild under their name
- Look for a class icon above their portrait
Method one doesn’t always work, however, because not everyone is in a guild. I thought that method two was foolproof until I came across this character with a warrior icon who was walking along a patrol path much like an NPC guard would. 
Is there a way to tell with certainty whether a character is a player or an NPC?
