Ok. I don't know what is wrong with everyone, but popping Sentinel, Hallowed Ground, Vengeance, or Thrill of Battle to eat 2x WW isn't hard. I don't know who decided that this was difficult. They jump, they come back, Friction, you hit the button, you eat the 2x WW. If this is somehow a difficult concept for you, maybe tanking isn't your thing and I don't know how you made it to Garuda EX when Titan HM employs the same concept. Rock Breaker -> Mountain Buster.

Anyway, the best possible strat is to split all 3 to different people. MT on Garuda, OT on Suparna and a melee on Chirada. Everyone (DPS + Heals) splits the Downburst damage, MT and OT take 1 wicked wheel, everything is 100% fine and 100% easier to manage. But only Japan does this because apparently no one else thinks that DPS can take damage and not die.
