I got the Reins of the Raven Lord achievement my second time farming it. Was pretty awesome.
I'd say my favorite is .It took me so long to finish it, but in the end it was so worth it. Purple dragon AND free 310% speed? Yes please.
For me it's Loremaster of Eastern Kingdoms achievement. I got it before Cata and I was almost done with Kalimdor. It took me sometime to get it and just to try to find quests to do. I was happy when I got it but no one in my guild was on at the time to grats me. It was hard for me since I get tired doing quests and go do something else.
The Frozen Throne (10 player) It's pretty much the entire reason I played the expansion, and the entire reason for my main to be a dk for the expansion. Its been the one driving factor ever since playing through wc3, and my gosh did it feel sooo good to finally kill the king! Not to mention the epic scale of the fight itself. And, to top it off it comes with a pretty neat title (though it lost its luster when everyone and their mother was sporting it.) But, yeah. That's been my most sought after "achievment" since before achievments existed, and the most satisfying one to finally get.
Undying in Naxx! Such a crazy rush to get it complete.
Yogg Saron kill! It was nothing special for most people but felt so good for the guild back then after dedicating so much efforts.
Mine will have to be Realm First! Grand Crusader. It came as a surprise as it was only our third try after killing heroic anub(25) for the first time. Between all the miss-timed holy wraths, healing going ld at P2, and our 'unhittable' offtank going down (we used 1 offtank for all 4 adds) it came as a wonder that we actually got this achievement without needing more time trying.
I play on a slower-progression RP server. During BC, only one guild on the server was pushing through Black Temple when it was current content (and then into Sunwell). Due to my husband's insistence and persistence, I managed to snag a spot in said guild as a shadow priest. This was before the attunement requirements were removed and I hadn't actually done any of the questline when I was admitted. Needless to say, I am very proud of my priest's Hand of A'dal title because I earned my spot in that raid and, later, our first pair of T6 priest bracers in Sunwell through hard work. It's also memorable because I did all of my best high-end raiding while pregnant - those T6 bracers? My last raid because I was only 2 weeks from my due date.
Insane in the Membrane, the moment I heard about it I decided that I would work for it and get before I quit playing WoW, if I ever decided to play a different game.
its over nine thousand achievement
It would have to be You're So Offensive for me. It got me my favorite title in the entire game.
I would have to say the "Stood in Fire", Since 5 of my alts have it and my main doesn't yet...Tired of chasing that rascal.
My favorite is Accomplished Angler simply because of the title!
