Proud of my Starcraft 2 Thor Pet Achievment :) I get him every time I make an alt :D
The Light of Dawn.
Completing the Trip on my fourth toon, after being forced to miss out on a few events due to computer problems. Felt good to gain it when I came back.
Never been a big achiever, but it felt great to finally take down Twilight Vanquisher, back on Naxx days.
I like the World Explorer achievement, because it shows you've been there, even if you haven't always done that. :)
Well, I'd have to say...The epic Warlock mount questline FoS.Yep, I know it's still possibly and can be done pretty easily now, but back then, it was just an awesome time having fun.It took me forever to find the money even though I didn't buy the costly items! I'm cheap...The quest chain itself was pretty entertaining. ESPECIALLY the last Boss. One of my most epic memories *tear*
The achievement I'm most proud of is 冰封王座（10人）, as I acquired it while the raid it comes from was current.However, my favorite achievement would have to be 小心“无敌”翼手龙 and the quests to go with it. Very unique mechanics to those quests.
Avast Ye, Admiral!Everytime I get a loot code, it feels like a ninja to redeem it! :D
列兵, I didn't even PvP back then much!
The Secrets of Ulduar (25 player), which we completed before ICC. That was the last major achievement of the guild I ran, before we broke apart.
My favorite achievement is 冰冻废土的勇士 because it made my mage's name super long and at the time it was a pretty rare title to have.
The achievement im most proud of would be when i did "FOR THE HORDE!" on my now level 55 hunter back during WOTLK.I went to do it on my level 60 warrior but during our run in on Stormwind an Elitist kicked us all out for not being level 80.So i went on my hunter in another realm and did it at around level 40 xD great times. We had a full Raid group and everything.
Zul'Aman timed event (阿曼尼战熊), definitely - it was amazing the work we put in to do it, and getting the group together for it.
The acheivement that I am most pround of would have to be 千奇百怪的漫长旅行. Why, because it took me a long time to get and the reward is awsome.
Easily What A Long, Strange Trip It's Been. Not only did it take a year, most of the various qualifying achievements were extremely hard, time consuming or required a whole lot of luck.
IT´S OVER NINE THOUSAND ! took me 3 years to complete it but finally i got it and i LOL a lot since i knew about that achievement long ago.
Mine is the Fool for Love achievement. *forever alone*
The achievement I'm most proud of...lets see here...I would have to say Loremaster. I don't quite have it yet, but I'm only 3 zones away. I'd be most proud of it because of the time i put into it. The achievement shows that I know this game. Also, I really enjoy WoW's story line, and reading all the quest....yes, i read each one, had me hooked. But, im also pretty proud of Veteran Nanny. I feel like an oldie with 4 years of WoW (I missed a year for Outland's.).And lastly... the What a Long, Strange Trip It's Been. It took a whole year, and I did it BEFORE I had the 310% Flying Speed Bribing me. Some of the achievements were a huge pain, and parts of me are thinking, "Glad I don't have to do this holiday again."I hope it's not bad I did 3. O.o
I like the 冰河踏破者的荣耀（10人） due to the epic looking mount it give you
Into the Wild Blue Yonder. It only requires a little bit of gold, but it represents a wonderful new freedom for alts.
