Having the MT tank Garuda and a sister and then expecting the OT to be able to Provoke off is a really boneheaded strategy and causes a lot of wipes regardless of skill because you're making the phase a lot more dangerous for no reason. What often happens is OT is forced to either ignore Suparna entirely or ignore Spiny, because Provoke has a cooldown that the vast majority of people neglect to factor in. A safer strategy all around is what is known as the triangle strategy. Simply put, after the party splits for tornadoes and the sisters spawn, MT takes Garuda, OT takes Suparna, the entire DPS/Healer pile takes Chirada. Chirada doesn't know Wicked Wheel and hits for comparatively less damage, meaning its very safe for a DPS to tank her for the short amount of time she's alive. This also means neither tank has to use provoke for anything but Spiny, lowering the chance of something bad happening there. This strategy is easier the more ranged you have but melee can use gap closers and/or ride the central tornado for the ~1.6k it does to get around with little fuss. This means no one eats double Wheel ever, it doesn't matter where the Spiny starts because both tanks will always have Provoke ready in a phase where it only needs to be used once, and its overall a much smoother method that won't cause unlucky wipes because you're demanding your OT perform physically impossible actions.
