Wicked Wheel is triggered about 5 seconds after Garuda's Slipstream or about 25-30 seconds after Garuda spawns adds. Make a macro to time it and you'll know when to move away. You can run between tornadoes or through them if they're not raging. There's a pulse that you can hear very easily. The OT should pull Chirada and provoke Spiny right at the spawn if he doesn't have aggro. You kill Chirada first then MT and OT switches Suparna and Spiny at 2 stacks. Easily done but some OT doesn't know how to. When Chirada is dead, Suparna can't do WW anymore so melees are completely safe 100% of the time.
What's the point? Because melees do tons of DPS. Just because you haven't figured out how to maximize your DPS doesn't mean others haven't. If the parties are only bringing ranged dps to the fight, they do not know the fight as well as they think they do.
