I differ slightly from many here in that I don't mind too much about Garrosh's decent into tyranny; perhaps only holding reservations with the starkness of the turn and the feeling that it comes as a departure from the character we knew. Notwithstanding that, I like his leadership style, and feel it is very 'horde'.
I love the feel of the Horde as an iron-fisted, totalitarian regime, as captured beautifully by this song, the Kor'kron presence, and Hellscream's leadership style. I wish it could stay this way. As a minion of the Horde war machine, I am more afraid of the taskmasters behind me, than of the alliance defending their homes ahead- I don't lack conviction, mind you; whatever my race, joining in the Horde is the best chance my reviled, disgraced, vulnerable, scattered, or downtrodden people has. We have to fight for a place in a world that doesn't want us, if that comes at the expense of the alliance, let them burn.
My main hope is, after toppling Hellscream, the Horde might develop a bit of a dysfunctional coup culture; diverse and treacherous factions united by necessity and mutual benefit, but constantly scheming and jostling amongst one another for greater influence and control. The Warchief could change every xpac, or even more frequently, and contrast nicely with the stability and unity of the alliance- where faction leaders collaborate equitably in a council format.
All in all, were mostly there:
- Silvermoon is ruled by a military junta, headed by the former head of the military turned 'Regent Lord'.
- Undercity is ruled by a ruthless and autocratic 'dark lady' who is wavering in her foundational commitment to free will, and transitioning from a fiercely defensive regime into one that embodies a threat to all neighbours.
- Orgrimmar is military mega-barracks under martial law.
- Bilgewater Harbour is the plutocratic factory of the Horde, and a giant gun, no less.
- The Echo Islands seem to form an exception, but not really- a minority ethnic group raising arms against the state is a hallmark of a failed state.
- Only Thunder Bluff stands as a peaceable and sane counter-example, but even then their leader was slain in a power grab against the Warcheif interfered with by a separatist traitor. The tauren are a people who, facing extinction, sold their soul to a Horde that turned out not to be exactly as advertised. Now they're entangled, and despite much horde-skepticism, are unlikely to actually disentangle themselves and leave (if indeed they would be permitted to do so).
We just need these corrupt and dysfunctional cultures of governance to 'trickle up' into the Horde executive. As a final caveat, I'm not saying I want the horde to be disney evil, or to abandon it's nobler and more hopeful elements; I want a horde that struggle with the fruits of authoritarianism and factional infighting, borne of it's unchecked, military dominated, executive branch. Contrasting that with high hope and good intentions is actually preferable- gotta love the conflict between moral characters and institutional resistance thereto.
TL;DRThe Horde being a dysfunctional junta, even in spite of it's high minded re-founding principles, suits it well- and should persist even if Garrosh is removed as Warchief. The problems under his rule are systemic, not solely drawn up to his flaws.
