Mine is the Hand of A'dal on my warlock. Was great to get the title back then, having killed two of the best bosses ever designed.

Insane In The Membrane is the achievement I am most proud of (Salty is actually a close second).I was planning to get it on my Rogue, who shares the same name as my Wowhead username =D... However, since my main had a head start, as he had the Bloodsail reputation, so I attempted to get the achievement on him. It felt pretty easy at first, killing some pirates here and turning in some items there, but the task became daunting almost immediately as I realized how much I had to turn in and kill. I stopped trying to get the achievement for several months until I saw blue posts that the achievement would be removed with the Shattering (even though there was a contradicting blue post). I was immediately spurred into a grindfest unlike any other. I tried not to spend too much money on the endeavor, picking off only the cheapest items from the AH to raise the reputations but as the market got crazier and crazier for items like Pristine Black Diamond and materials for Rogues Decks I soon began to sink thousands of gold just to increase my reputation. I managed to finish each reputation, one by one. The Ravenholdt reputation encompassed of a couple months of on-and-off junkbox farming. The reputation was ultimately pretty easy to finish and that wasn't the reputation I frantically needed to finish before the Shattering. I focused more heavily on Shen'dralar and the goblin reputations, knowing that the former, at least, was likely to be impossible after the Shattering. For the goblin reputations I killed a few thousand pirates, but ultimately I chose the path of "Dire Maul Shackle Key" runs for the reason that I needed to also increase my Shen'dralar reputation. After finishing with the goblins, I began to farm over two hundred Blood of Heroes in order to improve Shen'dralar reputation. With the items I bought from the Auction House and the Blood of Heroes, I was able to finish the Shen'dralar right before the Shattering came. I only had Darkmoon Faire to do at that point. I was already steadily raising that reputation by farming herbs in Silverpine Forest for Rogues Decks. It was a frantic rush to get the reputation finished before the Shattering, but to no avail. Supply ran out before I was even halfway through Revered with the Darkmoon Faire. After the Shattering, I discovered a new place to farm in Hillsbrad Foothills. I even realized it was possible to still finish Darkmoon Faire. As much as I would have liked to have gotten the original version of the achievement, I pushed on, spending but a few days to construct the few hundred more Rogues Decks I would need to become Insane. When the time came, I gathered all my friends, called the Darkmoon Fortune Teller, and turned in my last deck. I immediately donned the title for my friends to see.And now I sit and wait...for a Postmaster title...
getting my raven lord mount on two of my characters, which took about 3 months per guy to get, but definitly worth it
undying need i say more :Por wat a long strange trip its been
Master of Arms on a resto druid (every obtainable skill, actually). Serves to show how much of a completionist I can be...
My favorite achievement Ohganot So Fast!, when my guild first did this achievement the raptor mount dropped! I didn't win... but was still neat.
Wild Hammering since DWARVES ARE HARD AS STONE
Mine would probably be the For The Children achcievement, which i got a few minuttes before the event ended.. I got though I had internet issues and my computer was plain laggy making the pvp-part of it unbearable. Also returning the flag three times without the orphan out when you only have half an hour is frustrating as hell >.<
Winterspring Frostsaber Getting the Winterspring Frostsaber back in the old days. Even with Human I'd get 83 rep per quest turn in and it literally took me weeks if not months of grinding it. After finally getting it I spent a few days just running around in Ironforge and answering all those questions of "Where did you get that mount?" 4 years later and I'm still loving my rather unique white kitty.
Champion of the Naaru Because I completed it when it was actually hard and got The Tempest Key.Got to say... doing that Heroic Shattered Halls with a rogue in the group was not fun!Mainly the most memorable as I was a mage and everyone wanted a mage for polymorph I was draged in and out of them heroics.It was hell. XDNot sure how many im supposed to link but if i were to pick a second, I would say 3000 Quests CompletedGot this 2 days after Wrath of the Lich King came out, pretty sure I was one of the first to get it hehe.
I am really proud of my "level 85" achievement, because a new world open when you are at the max level, that's quite a task getting there from scratch and we forget how much this represent.
Loremaster is probably the achievement I'm most proud of. I think a majority of WoW's players don't really have such an investment in the story and the lore and it makes it that much more special when you're one of the guys who knows what they're talking about.
My favorite achievement (choosing is so hard XD) is It's Over Nine Thousand! (i still trying to get it, almost there), i dont know why but the reference and the number of achievements you need to get to complete this one is just epic, even if its a FoS and doesnt reward anything.
