Bullshit. Garrosh only do brute force when he is sure he can win.
In ashenvale he hides his army in smoke like a rogue to ambush.
In ashenvale he kidnaps baby Magnataurs to force their moms to fight for him.
In ashenvale he enslaves proto drakes for his next big weapon.
In the Barrens he has shamans enslave elementals to do his fighting for him.
In Theremore he has a mana bomb do his fighting for him.
In Durator he enslaves Krakens to fight the alliance fleet for him.
In Kunlai summit he use the bell as his next big weapon.
In Ogrimmar he uses the heart as his final weapon
And the number one cowardly douchebag thing... In ashenvale he sends wave after waves of orcs after Varian knowing that Varian would kill them just so mr chin would be weak enough for him to have an easy victory.
He doesn't act like a warrior, tho I don't believe the leader of the horde's answer to everything should be to charge in head long, however he hides the word honor when he never had any. Not by Orc standards or anyone else for that matter.

You are really grasping if you claim the alliance one and the horde ones are the same. On the horde side we just told pandarens to walk away and they complain about working conditions. According to that link on alliance side, horde actually kidnap their kids.
