I'm not exactly new any more but I've never really thought about this particular question before. And I didn't see this answered when I searched around.

The threat level I see next to mob health bars -- is that the color it is for only me or for the whole group?

I ask this because I was curious if a high level character joining a party of low levels messes up their experience. Obviously the high level player is gonna see gray threat levels=no experience on the mobs.

So, is the color always individualized based on your level compared to the mob?
