Tornado Kick usage

[Atreides]

Tornado kick should only ever be used if there is absolutely NO way to safe your GL3 stacks.
In other words it's a situational skill that only shines in a few fights where your target disappears for a long enough that you can't keep your GL3 up by the time he lands or as finisher when the boss is about to die anyway.

There are a few raid encounters where you can actually make use of Tornado Kick:
Bismarck to finish the Fin or right before you go off.
Ravana Whenever he jumps (Bonus if he's Vulnurable.)
A1 before the boss takes off.
A3 right before the add phase starts.

Other than that, shits about to die? Tornado Kick.
I'd rather have Dream within a Dream.

Using Tornado Kick in your normal rotation is a DPS loss.
