During tornado phase, if we go dps Suparna we have to watch out for Wicked Wheel which has no warning, it hits 360 degrees and can one-shot my monk with 4300 hp. I keep an eye on Friction being cast by Suparna then I move away from her but there is barely any room between the tornadoes to dodge it.

If we kill Chirada first, like most groups like to do, the OT might take too long to peel Suparna off the MT due to using Provoke on Spiny, we run out of time and Garuda wipes the raid with Aerial Blast for 25k dmg. My choices are to wait and hope the OT pulls Suparna south in time or go where the MT has Garuda/Suparna and hope I can dodge TWO Wicked Wheels which has yet to work for me.

If we pull Suparna south first, we still need to deal with Wicked Wheel in a tight space but at least it's only one. What's the point of bringing melees to this fight at all?

It's to the point that parties are only bringing ranged dps to the fight.
