Difference between HB, WoW and Wowhead classifications...

[LiquidAtoR]

I've been in the process of making some farming profiles for my specific needs (crafting needs that is, not rep grinds).

Now I noticed that the HB target info (target npc and click button on the profiles and meshes tab) and the WoW and Wowhead info don't match.
For example:

HB target info:

Information about Skettis Soulcaller:
Name = Skettis Soulcaller
Wowhead Id = 21911
Faction = 90 [Demon]
Location = <-3684.084, 3740.411, 278.5929>
<vendor name="Skettis Soulcaller" entry="21911" type="Repair" x="-3684.084" y="3740.411" z="278.5929">

HB classifies this target as Demon class.
However WoW (in-game display) and Wowhead marks this target as Humanoid, and it's CC'able as such.

How come there is a difference between what HB says it is, and WoW and Wowhead says it is, and furthermore, does this have any influence on performance?

Thanks, Liquid.

The faction it belongs to is called demon, could also be called bootybay or whatever you like, and it still is a humanoid as creaturetype. The faction id 90 is just called demon for internal use i would say
