↖ Number 10: Franklin Martin & Koak Hoburn

At the tenth spot, we have a dynamic duo of dutiful drivers - Franklin Martin and Koak Hoburn. These NPCs drive the Chauffeur Chopper mounts for Alliance and Horde players, respectively. The Chauffeur Chopper is a unique mount that grants players a convenient travel option. Franklin Martin, resembling a character from the film "The Transporter," drives the Alliance version, while Koak Hoburn drives the Horde equivalent. These NPCs allow players to bypass riding training and enjoy the benefits of chauffeured travel, especially useful before the level squish. However, their usefulness has slightly diminished due to changes.

↖ Number 9: Ta'hsup & Lindormi

In the ninth place, we have another dynamic duo - Ta'hsup and Lindormi. These NPCs are Keystone Traders, allowing players to manage their Mythic+ keystones. With the Mythic+ system, players can now reroll their keystone, providing more flexibility and control over their dungeon challenges. Ta'hsup started in Shadowlands, and Lindormi replaced him in Draenor. These NPCs are essential for players engaging in high-level dungeon content.

↖ Number 7: Merchant Maku & Collector Unta

At number seven, we have Merchant Maku and Collector Unta, two tortolans atop The Mighty Caravan Brutusaur mount. This mount, available for a hefty sum of gold, offers players access to an auctioneer and vendor services on the go. Though impressive, the mount's constant access to the auction house might only be as essential for some players.

↖ Number 6: Cousin Slowhands & Mystic Birdhat

In the sixth place, we find Cousin Slowhands and Mystic Birdhat on The Grand Expedition Yak mount. This mount offers players a portable transmogrification and repair service.

Chromie's presence facilitates time travel and offers players the Chromie Time feature, allowing them to choose the expansion they want to level through. Her appearances across different zones ensure a smoother levelling experience and flexible content engagement.

↖ Number 3: Zidormi

Taking the third spot is Zidormi, another bronze dragon, who plays a critical role in allowing players to switch between different phases of zones. Her appearances across various zones make her crucial for players seeking to experience content before or after specific events, adding depth to WoW's history.

↖ Number 2: Katy Stampwhistle
