Demon Hunter - Illidian of course ...
Hunters need Swamplord Musel'Ek as a Combat Ally.
He will allow us to tame druids of opposing factions.
The entire Death Knight order hall mission chain is about resurrecting dead heroes, and the Warriors' hall is where the greatest(currently only Vrykul) Warriors go when they die. Either class could get either character as a champion.
I mean, it would be incredibly stupid and be nothing but a ridiculous fan-service that would actively detract from the story, but it wouldn't be outside the realm of possibility for either class.
Since hunters already have Hemet they'll probably throw his son into the action. Though a part of me really wishes Nathanos Blightcaller would be added to the roster.
Only thing I can think of is they want to you have a reason to rotate followers out based on counters or they're looking to smooth out some of the counters for various classes so you're free to pick from say 3 for each Spec/Counter, instead of feeling like you're forced to take 1 specific follower because it has highly desirable traits, such as mission reduction time or synergy with specific forces.
But yeah, considering it takes a ton of missions to level to Epic quality there's very little chance I'd swap out. Unless they make all followers bodyguards and let you have 5 with a designated bodyguard. At least then you could safely level up your extras through World Quests without having to worry about being able to counter everything.
There's already far too many (ie, all of them).
I would like to see Vandal appear sometime in the Demon Hunter Class Hall, or the unnamed female Demon Hunter in the Harbingers video.
Dezco for sure. Maybe turalyon? Not sure about that one. But definitely Dezco.
I want the Eredar Twins on my warlock as a permanent bodyguard....
For academic purposes..
Obviously.. *cough*
