Despite how the Second War ended, Doomhammer showed to be able to make this kind of choices; Grommash not, he has ever been brash, reckless and gullible. Grom has been the first orc to drink the blood of Mannoroth, blindly beliving all the bullshit that Gul'dan dragged out; Doomhammer cheated Blackhand (not a hard thing since Blackhand was a retard, but alas) by inventing a smart excuse for not drinking it. That's the difference.
The only mistake that Doomhammer commited was trusting Gul'dan out of necessity. But he had little choices in the end if he wanted to have any chance of victory against the Alliance of Lordaeron. Pretty a lose-lose situation.
I actually loved Garrosh, and was very happy when he became leader of the Horde.
I was hoping that they would have taken the game into a different direction.
In a direction that had the Horde become bad guys with select individuals leaving the horde to do their own thing.
Having an expansion based on invasions of certain major cities would be awesome. Alliance raids Org and Horde could have raided SW. Equalivant stat items could drop just from different raids/ bosses.
I liked a darker Horde... This whole two sides from different points of view... (both good guys) is dull and been like this since vanilla pretty much.
Garrosh, the lump, was removed, but the orcs were left shattered and weakened by what he did to there society that was just butchered by the alliance and rebellion (so much so the orcs are so weak now they have a .. troll as warchief).
Again, tell me where any good came from Garrosh? None, no good came from him, countless orcs are dead now, and its race within the horde is now facing an uncertain future.
Garrosh is amazing because he is nicolas cage of azeroth.
Look, they are basically same person.
Uncertain future = far far far better storytelling than just go on with what they already had going for them.
