I said sounds like
What i posted is merely opinion and the fact that i am defending my faction that is all
But im right when i say Wrathion isnt at the siege so what he hears is second hand information it shouldnt be regarded as fact
Now obviously we dont know what side is canonical but i would hazard a guess and say the allies suffers as much as the horde landing party does at the beachhead and that only us heroes manage to break the siege to get to garrosh where by the sounds of it thrall is waiting.
Now this leads me to believe the allies wont be in strength at orgrimmar when this is all said and done now sure if varian wishes to come back with more hard pipe hitting brothers to go to work on orgrimmar then sure i will give you that but by the sounds of it he wont
Notice how i say the word by the sounds of it not stating fact
