I Can't Hear You Over the Sound of How Awesome I Am would have to be my favorite. I love the name of it and it's certainly something worth recognizing for a group able to pull it off.
for the horde on my main because it took me so long to find a group then once i did, it wiped on the last one, storming stormwind, then i had to wait 3 months to find another
For me it is all about "It's Over Nine Thousand" mostly for the fact its an achievement about getting achievements, and it was a race between me and a guildie that I won.
For me it would be Insane in the Membrane. It took a lot of work to get it and I love the warning label it gives me. Getting it while i was raiding in Wrath took a while. Either that or my FOS for completing my druid flight form quest.
I'm gonna have to go with the Knuckle Sandwich achievement, since turned into a Feat of Strength. My main is a Death Knight and I run it as a tank, so it took me a while to be able to get this, with many deaths. Lucky for me, I was able to get it a bit before they took it out!
I'm most proud of what I did in TBC, but for actual achievements I have...Probably The Twilight Zone (10 player).I did it a while before Ulduar came out and days before people posted the challenge-ruining burndown strat. The original recipe called for killing all three drakes as fast as you can as they come, and it was complicated, frustrating, really fast-paced, and a lot of fun for masochists like me. People in greens were getting it done by the time Icecrown came out, so everyone who played in Wrath has it now.
For the Alliance! I remember doing this one at L75 during WotLK. Nothing was more fun that storming each of the required cities, especially Thunder Bluff.
Wrecking Ball was gotten in one hell of an AV. Massive battle, tons of fun, I was owning (rogue)... The real thanks goes out to that Staghelm-US ret pally Gladiator who LoH'd me at 29 HP when I was 18-0.
My Achive serves as a reminder that this is not World Of Ichoosewheniwanttodiecraft but World of WtfiwascheckingtheAHandnowimdeadcraft.World PVP 4 lyfe.
Exalted Argent Champion of the HordeSince I first met the Argent Dawn Recruiters at the Bulwark, I was a crusader at heart. Here was Azeroth's future, today. Faction squabbles and disputes left by the wayside for a greater cause and a brighter future. Thanks to this, I was finally able to display my allegiance for all to see. FOR THE DAWN!
toss up for me between Spirit of Competition or Gruntboth of these are my were my trump cards when I got into a "Most Impressive Pet/Title" battle, didnt always win but they were still rare
The achievement for.killing the plague quarter
mine would be "glory of the ulduar raider"
ChargerCompleted the paladin quest to obtain a Charger.
The Brewmaster achievement. Reminds me of Pandaren. They're awesome.
I like my Glory of the Icecrown Raider (10 player) :)
For me it was The Fifth Element for 3 reasons:1) Because it was the Very first Feat of Strenght i ever obtained, much to the surprise to my guild (and some on dismay too!, the envyyyy, since i obtained sometime after the achievement system came out, so those who had it wouldnt ever see the blink on the screen, much less new players know about it!)2)It uses the name placeholder of one of my favorite Movies and actors! yes, im a Bruce Willis "fan" and i really like most of his movies, The fift Element included3) Exhalted with the Hidraxian Waterlords (although its not part of the feat), it shows how many hours i spent doing their quests and of course, grinding my theeth on Molten Core!Cheers!
Mountain o' Mounts, because the endless whispers and /salutes make me feel very proud as I fly around on my Blue Dragonhawk
Personally, my favorite achievement was Herald of the Titans because no matter what the current content was you werent able to use youre overgeared sets for ulduar but instead had to use a gear level of 226 or lower. Making it extremely difficult to down algalon.
Do guild achievements count? If so, I'm most proud of our current accomplishment, The Bastion of Twilight Guild RunWe wiped for weeks and weeks and weeks, and we finally got it just last night. I, as one of the three healers (And the lowest geared of the raid group), am very proud of myself, and my raiding team. Due to me having to change characters so our raid group could continue progressing (2 times, mind you. It kind of sucks, actually.), the character that healed that kill does not have the regular Bastion of Twilight achievement. But, when next week rolls around, my guild is going to go through BoT again, to get me that achievement.If guild achievements don't count, then they should. But, I'd have to say For The Alliance!. We rallied as many of our guild members as we could, and pug'd the rest, but it was one hell of a fight. Getting as many people as we did (I forgot the exact number) to work together was quite a task (Especially for my realm...), but killing the leaders was much harder.
