Mounts are a much sought after form of transportation in which players ride atop the backs of various more or less exotic beasts (or machinations). Warlocks, Paladins and Death Knights can learn to summon mounts as a class perk. Mounted travel is definitely faster than walking, and The Burning Crusade expansion introduced flying mounts.

Mounts were generally expensive in the past, but their prices have been reduced while the training to ride them increased in order to compensate. However, some mounts do not cost any gold or Marks of Honor and will drop at very low rates from bosses in instances such as Stratholme, Zul’Gurub, Tempest Keep, Magisters’ Terrace, Sethekk Halls, Karazhan, Utgarde Pinnacle, and Obsidian Sanctum.
