Pretty easy way to do "Keeping it in the Family"

[Bupko]

As you know the main aim of achievement is to make nefarian 50% until air phase ends
so:

1) you need 3 shamans with hit cap
2) nef must be <70% until air phase starts
3) on air phase bl is casted and everybody hit nef (don' touch adds - shaman must interrupt all casts)
4) when phase ends we had nearly 45% of nef total hp and 3 mobs alive
5) then everybody jump on the ground (anyone who will be on columns will die)
6) adds on columns during 3rd phase shouldn't be tanked - only 3 shamans while standing on the ground interrupt mobs casts (only shaman because they have range interraption of casts Wind Shear - Spell - World of Warcraft

This. No rep since you acted like you found it out yourself.

I honestly don't see how this is a copy paste.
This has nothing to do with what Immersion did, because this tactic is just plain wrong.

You think you can leave adds alive, but I'm afraid this can't be done. When the adds die P3 will starts. I know this from personal experience and WoWWiki.

What you should be doing, and what Immersion did, is to outgear the content and find proper players. You will need an insane DPS to do this while still having healers to survive the incoming damage.

Turns out you're just plain WRONG. Phase 3 starts after all the adds are dead OR 3 minutes. Time to go back to WOWWIKI

To the OP. This is pretty unlikely because you're essentially wasting 3DPS because a missing healer will probably result in a add tank wipe or a very slow kill which will result in a wipe. The only way this COULD be possible is if all of your shaman are toping parses sub #200 and they have the reaction time to kick w/ a focus macro. One mess up could result in a wipe though.

I quote the achievement in focus here:

Damage Nefarian below 50% health before he lands for the final confrontation and then defeat Nefarian in Blackwing Descent.

It says "BEFORE HE LANDS". So this tactic must be absolutely useless as he goes to P3 after 3 minutes? I assumed he wiped the raid as he does in P1 if you don't manage to kill Onyxia in time.
If it does however work I'd assume its a bug.. Have you actually killed it this way, OP?

[Bupko]

yes we had 16 dpsers 3 had them melee (1 mob was dead) another 2 were alive until the end of the fight (2 shamans interrupted them)

[Albaek]

In that case it seems to be more of an exploit rather than an actual tactic. Thanks anyway +rep.

Ok , this probally wont work . . . ever . . . the big problem with getting nef down to 50% in p2 is that it drains healers , not interrupts. I`m a tank and i`m the top interruptor , i dont have 3% hit >.> you just have out gear nef by a little on dps , if you get 3 electrocutes in p1 , the achiev is cake .

- Just get 3 electrocutes on p1
- Kill 2 adds and slow down / stop the dps on the 3rd add plataform ( make sure to have your best interrupts on that one ( aka me and my bad rogue `-` ) and make ur raid dps nef to 50% .
- Then kill the 3rd add and just start screaming on vent like you always do on p3 ( is it just my guild >.< ? )
-Profitz ??

Btw , i remind you that you have to kill ony before she thunder blows your raid asses into cosmic dust, so seriously , dps run, its all about draining nef every last bit possible without killing your raid and if you have enought dps it just happens.
