Dust Devil Dancers

Any tips for this achievement? The one in GP to dodge the tornadoes on the second boss.

Dodge em, there is a couple of random savespots, not 100% safe, but yeah thats it.
Gotten it twice (main/alt) you just need a group that's better then average.

Have your raid stack up on the ledge behind the boss.
Have all your Warriors run Way of the Mountain so they can participate too, including the tank if he's a Warrior.
Once everyone learns to move together out of the AOE puddles from one side of the ledge to the other, the achi is yours for the taking ^.^

the tent behind the boss has an awning
everyone stack under it
you will still have to turn away and when you have to run just 180 and run on the spot into the tent

Alternative method to the above:

Use two tanks.

Like above, have the main raid stack at the tents behind the boss with the primary tank (boss doesn't cleave). Obey all the normal mechanics, strafing left and right when you have to run.

The other tank stands at the wall on the right as you go in. There is a little indent into that wall which is a safe spot when a dust devil is nearby. The tank can taunt the add to here and tank it (along with the add-add) for the duration of the fight (these don't have to die).

As the only target at range, this tank will then get all the aoe puddles cast at them and can move out of it when there is no dust devil nearby and can survive standing in it when that is not an option. This tank only has to make sure he/she comes back into LoS/range for heals every so often as well as obeying the rest of the normal mechanics of the fight.

Once everyone is used to their new position this should be relatively easy to achieve as only the add tank has to worry about dust devils.

If you want to run a gimmick spec, this tank could have Way of the Mountain and not even have to dodge the dust devils, trivialising this achievement completely.

1 lovely tip to make it easymode, use rogue tank, interrupt the run/jump phases precasts.....

Love that bug, nobody expects you to interrupt that precast...
