Hes prbly a Dreadlord, Maybe Varimathras we will have to see how he & Sylvanas react to one another if they even do.
I don't always hunt things, But when I do, It's because they're things & I'm a Bear.
Masters is a long shot. Warlocks and especially Demon Hunters can see through their disguises with ease, they are good at manipulating and tricking those whom aren't familiar with their magic or maintain strict ignorance of it, like the Scarlet Crusade. While Garrosh may be ignorant, he has Orcish Warlocks under his command, you'd think they would notice right away or at least be somewhat suspicious. I just can't see a Warlock being worth a crap if they aren't able to discern a demon from a humanoid, even with a guise up.

she* and whom are you? No one of merit... btw it's not "orcs killing night elves" it's "cdev killing the story".
A lesser demon sure, but Nathrezim are the burning legions elite agents.
Also I think you are overstating the power of the average warlock, most of whom barter with demons for power, and do not have any great mastery over them or have been shown to be in any way immune to their tricks. Actually the reverse is true... historically most people in the warcraft universe who toy with demons get the shaft in the end.
