How appropriate that you have a chimp as your avatar. If you want to be more appropriate you may want to go with something less evolved. Maybe invertebrates are good place to start.

Oh, yeah. Arthas will TOTALLY be downed in two days after release.

By Ensidia, not you. So shut your mouth.

I'm not sure why people downrated this response. It's generally true.

People ask for these sort of achievements as both proof that you know the fights (though since some of the fights differ between 10- and 25-man, it's a little ridiculous) and to make sure you won't be rolling on "their loot".

The idea behind it is that you've already been through heroic Naxx and have the things you want, so you're not going to need to roll on the stuff in this instance now, which means more chance to get what the advertiser of the raid wants.

Frankly, I'd rather have people ask for the normal-mode achievement, or better yet, just be honest about it and come right out and say "I want loot here, don't come if you're gonna roll against me".

I see that every once in awhile for VOA, someone will put together a group and say "full on (class x)" and then they're the only one in the group. Best part is when a piece of loot drops that they already have, and then no one gets it. Makes everyone feel real good about it, I'm sure.

It's just the same as on AM-H for our three times daily "For the Horde!" runs. Always advertised as 75+ only, but if you look, all of the organizers are 71-73. The people who have requirements like this usually don't meet them themselves, they just put them up to ensure that they are getting a group that can carry them/not roll on their loot. It's ridiculous, and the solution is to do exactly as the original source did: roll your own PuG. It's a pain, but if you set reasonable requirements, you should be able to clear the raid just fine (and you might steal some of the really well-geared players from the jerk PuGs).
