The simplest method is to have the main tank take Chirada (instead of Suparna as commonly known). While off tank is tanking Suparna, melee will still eat Wicked Wheel in the face but without suffering double WW (Garuda's share). It will only drop a decent geared melee to half HP, which can be easily topped off by the healers.

Afterwards, depending on which tank has spiny plume, the melee can dps at the off tank's or main tank's position as desired. One more Wicked Wheel will be casted by Garuda but it will not be enough to kill the melee.
