We've always had OT pulling Chirada (which we kill first) while MT pulls Suparna. Chirada dies when Garuda and Suparna land from their jump and that's when everyone moves to kill Suparna. During tornados we have MT and OT on opposite sides of area, healers and ranged DDs split in the two free slots (melees have to move from one clone to another).

Is there any reason not to do it like this? I haven't really considered any other strategies as this works well for us.

What is the "normal strategy" anyway? Is it what my group does or something else?
