Glory of the Dominant Raider

Name A better Duo, I'll wait

For this achievement you'll need to 2-3 players to pick the power "Oddly Intangible Key"
During the Tarragrue fight 2-3 players will run around during the Hungering Mist mechanic to find Buttons, once you've found him click on him and carry him over to Moriaz

Eye Wish You Were Here

For this achievement you'll have to do the fight as normal until 30% or lower, once at 30% have one player pick up the Lost Field Kit. Have the raid spread out in-between the boss and the personal holding the camera to take a picture of the raid and the boss, you might have to take two pictures the camera can be buggy some times.

To the Nines

For this achievement I recommend you three tank and overheal, the fight has an extremely long enrage time allowing you to under dps it on normal. I also recommend tanking a tank that does well with magic damage.
Have one tank stand out of the raid as you single target players who get the Fragments of Destiny until they've 9 stacks, once at 9 stacks dispel them and finish the fight as normal.

I used to Bullseye Deeprun Rats Back Home

For this achievement you'll need to burn the boss down to 30% as fast as possible then stop. On the left side of the room there's two hoops attached to chains, one doesn't move at all while the other swings back and forth, you need players to pick up the Orb of Torment and throw them through the two hoops.
I found the best time to do this was as the hoop that swings reaches it's apex, by the time it is lined up with the other hoop the orb should pass right through both of them.

Tormentor's Tango

For this achievement everyone in the raid needs to target Garrosh Hellscream before the encounter and /taunt him. During the encounter you need to avoid being him by the Torment cast.

Whack-A-Soul

This achievement was personally one of my favorites as it made the fight overall more enjoyable.

For this achievement you'll need to pull a leaver outside of where you fight the boss to the left of the bridge. I recommend holding the boss in the center of the room while having your tanks take the Cruciform Axe, Reverberating Hammer and Dualblade Scythe to one of the four corner in the room.
While engaged with the boss two adds will spawn at random locations in the room (Note: they can spawn during intermission depending on the group damage) the adds need to be killed fast while also interrupted if a cast gets off everyone in the raid will be feared for a short duration.

Knowledge is Power

For this achievement I recommend three tanking to help manage the sunder damage on the tanks.
Before pulling the boss there's a mob called Vazzaren to the left of the room before you cross the bridge. Pull him in to the arena and manage interrupts while avoiding the knock back this mob does. Do the fight normally and bring the add in to the Energy cores and kill it before finishing the fight.

Flawless Fate

This is personal achievement.
Defeat Fatescribe Roh-Kalo without taking damage from Fate Fragment's, Fated Conjunction, or explosions from Call of Eternity and Echo of Eternity.

Together Forever

To get this achievement you have to find Mr. Bigglesworth after Tarragrue and on the Floor with Painsmith then the Cat will spawn in the Room for Kel'Thuzad and you can put him on your head. When you have the cat on your head you need to enter the Phylactery and use your extra action button to deliver the cat and he will receive a 500% more damage buff. Complete the fight and you get the achievement

This World is a Prism

For this fight you'll need one person of each covenant to pick up four different orbs.

During phase two of the Sylvanas Windrunner fight you need to find the four different orbs on the chains and use them in the order that you picked them up on their respective platforms. To use the orbs all you need to do is walk on to the sigils in the order that you picked up the orbs and then finish the fight as normal.
When doing this my group found it easiest if the DPS did it while the healers and tanks stayed on the first platform you land on when entering phase 3
