This was such a well designed zone from a story perspective. The main plot arc is consistant throughout the zone and really hits close to some of the key story points I wanted to see relating to the Horde in this expansion.
The biggest draw in the zone for me was Krom'gar and the events leading up to the dropping of the bomb. As a character, Krom'gar is fantastic because he represents two things: first, he represents the kind of militaristic mindset the Horde has re-adopted since Garrosh's takeover. He's brutal, efficient and pragmatic to the point where he berates his own soldiers for not being brutal enough, using the defense of their families and questioning their loyalty to the warchief to do it.
The second thing he represents, however, is slightly contradictory to this; he misinterprets Garrosh's desire for conquest as being completely pragmatic to the point where he's unreasonabley merciless. The biggest emotional moment in the quest for me was when you realise false evidence had been planted to justify using the bomb on the druids of Thal'darah Grove. (I honestly felt a bit of political commentary there in regards to the Iraq war and the alleged WMDs used to justify it) To me this was an emotional high point, but also a low point; it validated my opinion on just how immoral the generals in the Horde were becoming, but being someone who liked Thrall's vision of the Horde more, it's not pleasant to realise this has become the reality of what the Horde is.
It's interesting; Krom'gar thought he was representing his Warchief's will. He thought Garrosh's vision of unbridled conquest meant even civilians and innocent non-combatants were viable targets. Yet when Garrosh finds out what happened, he kills Krom'gar. I think it's a great moment because it sends different messages to different people. To the people who support him, it's a warning that despite his brutal goals, it doesn't mean he sacrifices honor and decency to do so. To the people who don't like him, it shows that he's not a complete monster and has some ability for mercy and compassion.
While I still have a problem with the fact other characters build him up as a military genius despite his more-than-questionable tactics, in Stonetalon you can definitely see what the writers are trying to convey with Garrosh. Hopefully we'll have more of this in the future and less Twilight Highlands-esque 'HURP DURP' moments.
So bravo to the minds behind this questline at Blizz. More like this, please! =D
