My take on Vol'jin as leader of horde:
Some people: "Too predictable, blizz sucks"
Other people: "Makes no sense, blizz sucks"
As you can see, on the internet it's possible for something to both make no sense, while also being predictable.
My point is: dramatic narrative requires foreshadowing. If you want "unpredictable" things, then you should have been happy if they made Ariel from The Little Mermaid warchief of the horde. Wouldn't have been able to predict THAT, no would you? But, then your complaint would be "wtf out of nowhere blizz, learn to write!" If you thought Vol'jin was "unexpected", then I don't know what you expected, as the only other 2 living characters that have had more scenes showing them as an effective leader of horde members are Thrall and Garrosh (one of whom just nearly dissolved the horde), leaving the only option that "makes more sense" than Vol'jin as Thrall (which would have honestly been surprising since he already was, which actually leaves Vol'jin as the only character that A)you can believe the actual horde members would follow and B) isn't strange in a meta, out-of-game sense).
Further point being, unpredictability isn't a sign of good writing. If you truly believe it makes sense to spend 2 years building up Vol'jin as a character and then actually promote a different character to warchief who is essentially unheard of (only way it would be unpredictable in any way) then first of all, you don't understand what the point of writing is (it's to create a coherent narrative in order to communicate some piece of data to a reader) and you don't understand the economic stupidity of spending all that time paying people to voice-act, animate, write dialogue for, etc, just so you can ignore that character.
The "it's too predictable" argument is possibly the most foolish one I've heard on the internet in the last 20 years.
Makes the most sense, however blizz giving it all the "unexpected" nonsense will have some people annoyed, and rightly so i might add.
cmon guys u all knew this was gonna happen when they gave vol'jin a new model and did nothing to the others :P
Their tribe was almost wiped out by a Sea-Witch with Naga/Murloc lackeys, this same group killed a bunch of Kul'Tiras soldiers.
Your comparison of farmers vs murlocs is like me saying "My level 1 can kill a peon, obviously he can kill Garrosh!". Game level =/= Power level.
What can Vol'Jin bring to the table? He'll be the same as Thrall but more of an unbearable dick. Why is Thrall following him?
Whats lost in all of this is how epic it would have been if you replaced voljin with basic campfire in the cinematic. Imagine thrall talking to the fire and the fire saying I speak for the horde. Blizz missed out on a truly great opportunity here. Oh well, there's always next year. Basic Campfire 2014!

"Vol'Jin is Warchief? But it has to be an Orc! What is Blizz playing at, there's so many better choices"
"Lor'themar is Warchief? I don't want no girly belf leading the horde lol"
"Thrall is Warchief? Lol gg Blizzard giving us same stupid Warchief that gave us Garrosh, makes no sense"
"Baine is Warchief? Lol we've barely seen him compared to the rest, he doesn't deserve it"
"Saurfang is Warchief? Lol he's too old and had no build up, stupid choice blizz"
No matter who was chosen, there was always going to be huge amounts of qq.
I love it mainly as an alliance player but also as an if-horde-then-troll player. I stopped my WoW hiatus to get the Darkspear Revolutionary title on my troll alt before it was gone - so I can really only be happy.
Thrall always was, is, and will be my true Warchief. Garrosh and Vol'jin werent/arent.
