After signing the armistice, the Horde didn't cede any territory, paid no reparations, didn't even say sorry lol. If anything they came out ahead. Sylvannas' army that she left behind was bigger than the combined forces of the Horde rebels and Anduin's army as stated by Alleria. That army is now merged with the rebels, while the Humans are forced to conscript farmers, as their soldiers have suffered mass casualties. The Horde gained two new big kingdoms Zandalar and Suramar, while the alliance only gained one, Kul'Tiras.
The Horde is now the undisputed power in Kalimdor, while having 2 mega cities in the middle of the continents (Suramar city and Dazar'alor) to the Alliance's 1 (Kul'Tiras), heck Broken isles might as well be considered Horde dominated territory since they not only have Surmamar, but Thunder Totem as well, while the Alliance has no mega hub on that mini continent. The Horde still retains a full fledged kingdom in the EK with direct access to the ocean. Horde's civilian population is largely unharmed, while the Alliance lost nearly their entire Night Elf civilian population who are now reduced to refugees.
Horde is in a much better place than the Alliance, which now has divided leadership and growing fissures in terms of their direction. This war was an unmitigated disaster for the Alliance, while the Horde, all things being equal, did very well.
