BLM: Fire III vs Fire

[GilbertLapine]

So I got in a PUG for Garuda HM the other day with some douche and his DPS meter that kept sceaming my DPS sucked and I was a "worthless sack of shit" because I used what, at least I perceive to be, the commonly accepted optimal DPS rotation of fire III > fire I + firestarter fire III > blizz III/thunderIII stuff. He started ranting that "if you use fire I you're doing it wrong." According to him his DPS in the fight was 120, and mine was 90.

Needless to say the party didn't turn out well, and afterwards I tested his ramblings with the FFXIV App parser on one of the dummies outside of Ul'dah. The numbers are a bit inflated as both my character and the dummy were stationary without interrupts to the rotations, but using the rotation he was championing (repeated fire III > blizzIII/thunderIII) I was maxing out at just over 180 DPS and bottoming out in the 150s, while my rotation was scoring anywhere from 190 to 225 depending on the firestarter proc and hitting lows in the 180s for the umbral ice cycle.

So.. my question to the community is this: am I crazy and is he right, or was he full of it?

Thanks.
