After using this module and leveling a Human Shaman to level 70, I noticed that Heroism was not listed at the trainer. If you race change to Draenei, Heroism was available to learn and upon learning, put into the correct skill tab, Enhancement. When you race change back to Human the spell is not listed at the trainer and its also placed in the "General" tab.
I did some digging and eventually found the solution, that is listed below.
The culprit to this issue is "SkillLineAbility.dbc".
Faction specific spells like Heroism(32182)/Bloodlust(2825) or Seal of Vengeance(31801)/Seal of Corruption(53736) have a "RaceMask" to their respective races. With ARAC, this needs to change to all races of that faction. So either 1101 for Alliance or 690 for Horde.
There are other spells that would fall into this category as well but not limited to the one listed below.
Alliance:
Heroism(32182)
Warhorse(13819)
Charger(23214)
Seal of Vengeance(31801)
Horde:
Bloodlust(2825)
Warhorse(34769)
Charger(34767)
Seal of Corruption(53736)
