The problem with allowing Turn 2 Rage strat

[synaesthetic]

I don't consider this strategy to be an exploit simply because Square could not possibly have let this get past QA unintentionally. The boss stops using all of its abilities when it "enrages," and only casts a pulsing AE that does not instantly kill anyone.

Think about that for a second. They had to intentionally turn off those abilities during the enrage. If they just added "have the boss start dropping massive AE damage after 12 minutes," don't you think it'd still be doing Allagan Rot, Gravity Field and Ballast, not to mention High Voltage and Piercing Laser?

It's not an exploit, since you are not actually taking advantage of a programming or logic error. I'd say it was intended as an alternate strategy, and so does Square-Enix.
