For AOE purposes you can also take Blizzard 2. Rotation would be like Raging Strikes > [swiftcast]Shadowflare > Bio 2 > Miasma > Bio > Contagion if you have Garuda > Bane > Miasma 2 > Blizzard 2 spam until dots need to be reapplied or you get swiftcast again to cast another shadowflare. If you have Garuda or Ifrit on obey you can micro manage their AOE ability too.
