My first attempt with using the "JP" triangle strategy for Garuda Ex!

+1 for truth.

Fairly simple to tank once you know the mechanics. With good DPS using the MT on Suparna/Garuda and OT/DPS on Chirada also makes the fight cake for Melee since they aren't worrying about dodging Wicked Wheel. With decent DPS you can go 2x Tanks, 5x DPS (2x Melee BRD 3x Ranged/Magic) 1x WHM and literally wreck Garuda.

The fastest I've seen the fight downed is the Howling Eye phase after the 2nd sister drop. (Yes 2nd, that quick!)

I'd also note that if MT has Suparna/Garuda in 2nd sisters phase, and OT Chirada/Spiny that post Chirada dying @ the 2 Stack mark the OT and MT can trade Spiny and Suparna or all the Melee and OT can gather together on the MT's side (PLD) and they can do Hallowed Ground which allows them to eat both Slipstreams without repercussions and allows DPS to open up on Garuda very quickly - you then move to the Howling Eye phase (by which point the LB bar should be capped @3) and the Melee DPS can again burn on Garuda and then Limit Break to finish her before she jumps (Mages/Ranged handling plumes).
