Leveling to 90 of course.
I'll be that guy, and go with some nostalgia. Getting my Dreadsteed back at 60. I felt like such a baller.
the bc collectors edition murloc, its not realy an accomplisment, but when i first started to play all ive ever wanted was a murloc pet once i found out they existed
Winning Drake of the North Wind the first time I seen it drop was a definite Fist Pump moment.
Win win win win win win win
Getting the Blazing Drake off Deathwing. We had everyone vote who they thought deserved it most and I won (although narrowly, but let's not talk about that ^^)
It'd have to be my Rivendare's Charger mount. I farmed that instance so many times and when it finally dropped it was awesome!
Winning the Swift Zulian Panther, as well as getting 'What a Strange Long Trip it's Been' for the first time back during Wrath.
Finishing Insane in the Membrane. Easily my proudest achievement.
Yeah! I´m sure I´ll win one.
I can't decide if I'd rather have a feldrake or a Magic Rooster, so you should probably give me both.
The thing I was happiest to get was 10-Man Glory of the ICC Raider Drake. I had run that as current content, and when my group broke up I was only 1 achievement short of the meta. It was nice to finally finish that up, even if it was so much later that the achieve was a breeze, because I had done so much of it legitimately that it sucked not to have it.
When I got my Twilight Drake... I'd been after that sucker for a long time. Favorite mount in the game.
The celestial dragon was one of the biggest achievements for me. It required a lot of farming, money, and patience.
I about lost my mind when I finally got the Swift White Hawkstrider mount.
My most exciting piece was my legendary gem. Seems like such a sweet accomplishment that even the LFR'er can do.
100 Mounts and finally obtaining a Dragonhawk mount!
Sulfuras and Thunderfury. That was so great feeling when using the Eye of Sulfuras in the Black Anvil, or getting Prince Thunderaan down and looting the Dormant Wind Kissed Blade.
"Guardian of Cenarius" Tittle.
Time Lost Proto Drake. Still looking. Still hopeful.
