Tracking Dots on the Beta Classic Chinchilla do not differentiate between NPC and Player or Enemy Player.

Unsure if this is even possible, I can't recall if the game even had separate tints between them.

That's how things were in Classic I'm afraid. Very little was displayed on the minimap back then and many things used the same blip (quest turn-ins are the same as tracked herbs/mines for instance).

This is the expected behaviour for Classic and I strongly believe it cannot be worked around.
