Hey I don't know shit about PitBull so I can't help you with the first part, but this code should work to remove the race of the target NPC:
Code:
Outline()
local dr,dg,db = DifficultyColor(unit)
local classification = Classification(unit)
if UnitIsPlayer(unit) then
local cr,cg,cb = ClassColor(unit)
return "|cff%02x%02x%02x%s|r |cff%02x%02x%02x%s|r",dr,dg,db,Level(unit),cr,cg,cb,Class(unit)
else
local classification = Classification(unit)
return "%s%s|cff%02x%02x%02x%s|r",classification or '',classification and ' ' or '',dr,dg,db,Level(unit)
end
Also I lived near SeaTac for about 15 years! Cheers.
