NPCs Paladins and Paladin/Paladin archetypes in other Blizzard games (like Yrel, who was just added to HOTS, Crusaders in HOTS/D3) have decent mobility through leaps, and after nearly 3 years of complaining about our awful mobility in WoW, we're still sitting here riding a horse that is easily disabled for a whole 3 seconds a minute.
I am so disappointed in the WoW class team right now... the HOTS devs get it, the D3 devs get it, even the quest/NPC WoW devs get it, why can't the WoW class devs get on the same damn page?
