Tanking addon - mark mob with highest threat
 

Is there an addon that automatically marks the mobs with the highest, second highest and third highest threat so that DPS know where to DPS?

Sushi Auto Mark or Kungaloosh maybe?

I don't use either just remember seeing they have the option to mark by threat.

It is a good idea, tracking the highest threat target the player has to then mark it with a skull, only problem to my knowledge is that there is no API that can return "all units involved in unit" to return full list of mobs in combat with player or a party member.

It will be difficult to get a overview of the situation -if a mob is not targeted by anyone then the addon will think it's not in combat (I guess an addon has to be based on target of target, party, raid units, e.g.)

Doable with some sort of logging I guess, but the mark wouldn't be possible to place unless someone have the mob on their target (could match that by GUID).
