Hey guys.
I'm not in to the whole speculation thing surrounding the next expansion really, i've just realised a few things, though.
I did the scenario " The Secrets of Ragefire", and I realised, during the last phase, there are these NPC's called Kor'kron dire Soldiers, now these soldiers are just the giant orc versions similar to raz in blackrock caverns was, but I realised, they have the Fel orc model, as in red skin, we've only ever seen this with Chaos orcs and the blood infused orcs from Hellfire Penninsula, and as far as we know, no Fel orcs ever joined the horde, I know that the dragonmaw clan did, and that they were also infused with the blood of demons, but you don't see any other red orcs at all during SoO or the scenario, just the Kor'kron dire soldiers ( or not that i've seen, anyway.)
The dragonmaw we see in SoO are black like Warlord Zaela.
Could this be any sort of possible spoiler towards Warlords of Draenor?
Another thing I noticed is that Gorehowl dissapears after 5.4 when Lor'themar and Jaina claim it in the room of the Sha of Pride
I noticed that some of the spoilers say that Medivh is involved in the next expansion ( whether as a hero or an enemy is yet to be determined).
Gorehowl drops from the last boss in Karazhan for seemingly no reason, and no explanation has ever been mentioned, another Spoiler also mentions that Garrosh continues to create the Dark portal.
Is it possible that the Dark Portal is complete, and Garrosh is involved in a raid at Karazhan, since Medivh is still evil at this point?
It'd explain why Gorehowl would end up in the hands of Prince Malchezzar, with Medivh gifting it to him for his participation in the battle for Karazhan?
It's a long shot sure, but Blizzard have worked two random pieces of lore together on more than one occasion, and multiple spoilers i've seen have said that Medivh and the dark portal may be involved in Warlords of Draenor, couple this together with the recent TCG pack - Betrayal of the Guardian, which a rare piece of loot is a Dark portal hearthstone, may hint at the future of the expansion yet.
It isn't unheard of for Blizz to do this kind of thing, in previous expansions they would add items with names pointing towards the expansion ahead.
This is just my 2 cents anyway, please feel free to decimate my conspiracy.
