My first mount (a kodo :) ), back when you had to be level 30. *sigh* nostalgia...
You know, what made me really happy back when you still got Master Riding for it, was my What a Long, Strange Trip it's been. It was great. Now I take pleasure in the small things, like my Giant Sewer Rat, or my Sea Turtle <3
I am really proud of my Swift Razzashi Raptor. I farmed ZG so many times at least I got one mount. :)
My Flametalon of Alysrazor. :)I've never had a lot of luck in game. And finally in 7 years of playing and month of boss farming BOOM ! My mount ! I was soooo happy. :D
Finally getting my ICC 25 man drake. It took so long to finish, but actually getting it at level made me feel really proud of myself and my guild for all that we had accomplished.
I have two favorites, one being my rocket that I got from inviting a friend because it allows me to transport someone with me. The other is the Lil'XT so I can break those stupid trains in the AH.
Doing the Timed run back in TBC for Zul'Aman and get to win the Amani War Bear :D and it was Realm First Mount and timed run ^^
Must have been when only three days after the release of Cataclysm I got the solve in archaeology for the Ultramarine Qiraji Battle Tank.
getting time lost proto drake ! I camped for long hours and seen it dead 3 times before getting it
Cloud serpents all the way, farmed onyx eggs the day i turned 90; love dem new models
It would have to be acquiring lvl 90 on 3 of my toons.
The new wyvern/gryphon mounts from the Landfall patch.
acquiring T6 on my druid
My death knight sure would look swanky riding around on a chicken mount... :D
Rivendare's Charger mount is the coolest mount ive seen
It was great to get the Cloud Serpent, but I think the Netherwing mount was the most boring, and therefore the most satisfying to finish!
In my quest for mimiron's head and invincible, which I am still working on, I have completed a total of nearly 20 Val'anyr, Hammer of Ancient Kings from Ulduar and about 25 Shadowmourne from Icecrown Citadel. That alone is my favorite accomplishment.
Reaching level 90. There's nothing more pleasant than being at the level cap. It's when the game actually starts.
