So far as I'm concerned making Garrosh behind the Stonetalon bombing, or at the least not as concerned about the loss of innocent lives than he first appeared is nothing more than a shameless retcon to make us hate Garrosh more and justify his abrupt turn into irredeemable evil. And quite frankly it was an unnecessary retcon. Why exactly did Garrosh have to become a mustache twirling villain to become MOP's Big Bad. I can see Cataclysm Garrosh grown desperate resorting to the use of the Sha and bringing the Alliance and Horde down on him and personally I think it would have been a lot more interesting.
But in fact, he did it so only because he felt on himself the pressure of both Thrall's and Saurfang's judgement, and while Thrall bursted out immediatily saying something like "this is a shameful and cowardly act!", Garrosh thought with himself something like "In the end, has been a good thing that the Alliance didn't get Mor'dethar". Just figure out.
1- Garrosh is smarter and almost cool-headed in some things, but displays a more cynical attitude. All of this could be easily explained with him, in fact, learning some tricks or two about how to be a "smart" leader, even if this for him meant just using a lot of deception and faked respect for the allies that in fact never seriously respected by the beginning, just for obtain what he wanted;
2- Garrosh is very full of himself in the novel, pretty egocentric and arrogant in a way which is pretty a step forward compared to Garrosh in Cata (that already shown signs of reckless arrogance and dictatorial attitudes). This seems just Garrosh becoming more aware of his effective power, that now was pretty huge thanks to all the Blackrock orcs like Malkorok that he added inside the Horde, which gave him enough military power to litterally "keep in hostage" his nearby allies.
His new advisor, Malkorok, gave him also the need of support and validation that Garrosh always desired, and Malkorok himself gave to Garrosh many "ideas" about how to effectively "keep in check" not only the Horde leaders but every member of the Horde, orcs included.
Because it's a game and the creators can give power to whomsoever they wish. Real politics would rarely apply here. I don't see what all the fuss is about.
I hope they wont, But blizzard have multipel times said " gameplay is more importen then lore" so even if orcs are always the main army, so most orcs have died, AND many orcs have joined Garrosh, somehow they are still the main force of the horde, and therefor they will still be in control.

This pretty much explains it.I hope they wont, But blizzard have multipel times said " gameplay is more importen then lore" so even if orcs are always the main army, so most orcs have died, AND many orcs have joined Garrosh, somehow they are still the main force of the horde, and therefor they will still be in control.
