Glory of the Icecrown Raider (10 player)

Having done these achievements a few weeks ago with our heavily overgeared group, I figured I should make a list and quick recap of tactics for each of the individual achievements. All of these were done on Normal mode, except for Gunship.

Hard

All You Can Eat - By far, the most frustrating achievement. We played normally until phase 3, where the second tank would take cover behind the first Ice Block. As soon as his stacks went off he'd run in and taunt, the previous tank would take cover behind the ice block. When this tanks' stacks were gone, he'd shout out to kill the Ice Block and run in and taunt, the other tank going to the next ice block. Repeat. It's mostly a matter of control. We lost this one week because someone lagged and didn't notice he blew the stacks. To combat this, I reccomend the addon Smorgasbord. Just remember to turn it off if you're not doing the achievement or you'll see massive amounts of spam.

Medium

Been Waiting a Long Time for This - Have the first person who gets the plague dispel it outside the group and just stack the remaining diseases. Nothing to hard, per se, but if you skip over 30 (say, having a 29 merge with a 2 giving you 31), you fail it, and it takes a bit of time. Furthermore, if you're short on DPS the Enrage timer might become troublesome.

Nausea, Heartburn, Indigestion - Simply don't slow the slimes. If you're not well geared bump this up a bit, as I imagine that, for a non-horribly overgeared group, this one could be pretty painful. The abom still has to eat the goo, but this does give him time to help out with DPS more, hurrying the fight along.

Full House - First, pray to your god of choice to make the RNG kind. This one can be very frustrating if you don't get the right mobs turned. Empowered adherents don't count, by the way, so feel free to kill those. We had a hunter kite the deformed around and our OT simply kept aggro on the other mobs and ran around. This does mean your MT will not have a lot of threat, so be careful. If you feel safe doing it, you could have your OT taunt off aswell, but then you have to make sure no one uses any abilities that deal even incidental AoE damage.

Portal Jockey - Do this with 4 healers, if possible. Send 3 in through the portals everytime. It makes the fight go by faster, though you might have some DPS issues if your group isn't quite that well geared yet.

Dances with Ooozes - I'm not sure how hard this is in a properly geared group. You can either merge 2 small ones into a big one, and merge that with another big one, still only increasing the stack by one, or doing what we did - simply leave everyone out and nuking on the boss, only having an OT ready in case a few melee get it and it grows in size.

Easy

Flu Shot Shortage - Have the first two people who get the debuff run out. Then, the next time, have the peopel that got the first batch run out and everyone should have one stack. Then for the third and final, have everyone clump up. Should someone get the debuff twice in a row, just make sure they run out on the third. This one's a bit RNG, I suppose - I guess there's a chance the same person gets the debuff 3 times in which case, just wipe it up and try again. The damage should be fairly easy to heal through.

Once Bitten, Twicy Shy - Not a very hard achievement, in fact, many will get it incidentally. That said, just arrange bite orders properly and if someone doesn't want to get bit, make sure they don't attack the boss until the first bite's gone out. If you can get her down in Heroic, you should not have any issues with biting the 'wrong' people. Will take more than one run to get, however.

I'm on a Boat - Split the raid into half. We left the cannoners on our ship at all times, so each jumping group consisted of 4 players - though you can arrange 5 peopel to jump, if you so chose. Have the first group jump the first two times, and then the second group the last two. After they land the second time, make sure they stay put on the ship in case there's a fifth freeze. Furthermore, don't have them jump around on the ship - It might count as landing an extra time.

Incidental

These ones you, essentially, get by killing the boss in question normally. If you're capable of doing the heroic modes, you probably have the achievements already. But, in case not...

Boned - Make sure that everyone attacks the bone spikes immedeatly. This can be rough in heroic because of the spikes popping up in the Bone Storm phase aswell, so you might want to do it on normal.

I've Gone and Made a Mess - Avoid the beasts like the plague, and don't stand to clumped up. Getting 3 debuffs is common in the Heroic version of the fight, so again, I advice doing this on normal.

The Orb Whisperer - Make sure that the tank on the Shadow guy has his stacks high, and soak as much as possible of the empower flame orbs when the fire guy has the orb.

Removed

Neck-Deep in Vile - This one's not required for the Meta anymore, and as such I haven't done it. It appearently requires pretty heavy ranged AoE stacking, but I really can't comment. It looks pretty rough, though.

I like the fact that the icon of this achievement is the best pally helm of all time :)

The honest answer is probably months. If you're gunning for the drake, your gear should be your last concern. The majority of the achievements for the meta require FIRST AND FORMOST a great raid composition and coordination. You are just one of ten players. It means squat if you have the best gear in the game if you have three others in the raid that insist on standing in fire/acid/slime for one second too long. Many of the fights require a perfect battle from start to finish to get this.

Take the achievement [Once Bitten, Twice Shy] for example. If you understand the fight mechanics (and you should for ALL fights to begin trying for the drake), you'll know that this is extremely hard for a ranged dps to get. The standard fight strategy has the first bitten be a ranged dps. Then that player bites one other ranged, on the 2nd round of bites the two ranged bite the last two ranged (or 1-2 melee as case may be). 3rd round all dps and healers will be bitten (4 bites x 2 = 8 vampires + 2 non-bitten tanks). The battle must be over before the 4th round of bites. For a dps to get the achievement if they have no off spec role (switching with a healer or tank, which locks can't do), two things must happen: the fight must end before the 3rd round of biting AND one of the players in 2nd round must bite a healer or another dps instead of you. That takes a raid that has the dps, coordination and planning ahead to do this.

My advice: find a good permanent raid group to go with, clear the whole raid including Arthas (necessary for heroic modes anyhow), then practice each fight to perfection. Along the way, you'll get the gear you need to do this. No shortcuts here...

There are guides out there for gearing any class/spec combination. You can even check RAWR to see what gear and enchants/gems are best upgrades for your spec.

P.S. Sorry for the wall of text, but I want to clear up the idea that "LOL I HAS UBER GEAR, THIS'LL BE EASY".
