Horde Races
Post here about the Horde races (Orc, Tauren, Undead, Troll) in general.
As announced by the BC site:
The new Horde Faction will be Blood Elves, with their own Faction Inate Abilities...

I also made an inter-faction table, which I will be able to link to later on...
(Note: Many of my notes were either moved or dis-hosted, so I had to make extra copies...)
But it pretty much gives an overview of the factions interaction and classes (as for balancing).

+ See the:

has a good display system on Hordes Factions Abilities...

There isn't much notes as to how to best apply them or what it's best for (or hindrances) but still...
