Thank you everyone for your answers.
Another quick question, is there a macro to change the tracking based on target?
In a TOC raid I forgot to change tracking from beasts, to undead to humanoid every round. I also forgot to change tracking from undead to dragons after coming out of of an ICC and into a RS raid.
As long as you track one of these races thats written on that talent, %5 damage will be active regardless of type of the enemy, just make sure you are not tracking hidden, herbs etc.
As for macro (taken by http://forum.warmane.com/showthread.php?t=199061)
Code:
/run for i=1,GetNumTrackingTypes() do local n, t, a, c = GetTrackingInfo(i); if string.find(n, UnitCreatureType("target")) then if t~=GetTrackingTexture(i) then SetTracking(i); end end end
