Even if they weren't, there was still this GLORIOUS event from the Second War when the orcs burnt down Quel'Thalas
Yeah. I doubt the elves were happy about that
At that, so what if they weren't the Blood Elves from TFT? The fact that they're Blood Elves and not High Elves means that they are grouped with Kael's group. Which means that they support his decisions. Which means they hate the Horde and like Illidan
Otherwise, they would be some crazy offshoot of high elf who no one likes
Kael'thas's Followers and the Blood Elves of Quel'thalas are two entirely different groups. The Followers of Kael'thas acitvely use demonic magiks and are becoming corrupted by it. The Quel'thalassians are comparable to the Ancients of Shen'dralar in that they hold demons captive and siphon what they need to survive. The denizens of the Realm Eternal apparently are highly displeased with the fact that Kael'thas sold his people to Illidan and has practically given himself over to corruption, otherwise he wouldn't be a raid boss.
As for their relations with the Horde, who says you have to like someone to be allied with them? They're with the Horde for their own benefit, I imagine they hold no true loyalty to Thrall in the same fashion as Sylvannas, though they may not be actively trying to kill everything.
Illidan's Forces: BLOOD ELVES NAGA NERUBIAN (Illidan must have met them on his way to the Frozen Throne. His soul mission is to destroy the Lich King. If the Nerubian's learnt this, they'de be like "Great! Semi-demon ally!") OUTLAND DEMONS (By killing Magtheradon, Illidan is the new king of Outland and all of Magtheridon's underlings now belong to him)
My appologies if I'm reviving an old thread...Mecheon gets a bit ratty about that -.-
You DO KNOW ITS AGAINST SITE RULES TO REVIVE OLD THREADS, RIGHT?
Anywho, I doubt the Nerubians would have allied with Illidan, and "demons" aren't a single race, they're a multitude of races
In all honesty, best things for an Illidan faction would be Blood Elves, Naga, Satyrs and Draenei. Lost Ones/Broken style Draenei, not Blue Ereder style
