Oh i went to stonetalon, and no he has no honor. He want his commanders to have the honor he doesnt have. he makes a massacre to a sinking alliance boat even when theyw ere no threat when he is returning from Northrend. Then he takes the kor'kron to try to massacre the quilboars only to almost get killed and almost losing Gorehowl, then he uses a bomb to destroy Theramore even when he killed the commander for doing such a thing.
he only has "honor" when that "honor" doesnt stop him from killing someone, which means he doesnt really have any honor.
And glory? No, he didnt brought Glory to the Horde either, he only brought shame, the same shame people like Gul'dan and Blackhand brought.
About land gained, yes if you took the times when Thrall didnt even tried to gain land Garrosh would have won more, even when he lost it after. The fact ios that Thrall gained A LOT more land than garrosh while he was Warchief. You are just handpicking a timeframe you choose just to make it look Garrosh is better than he is
