My dps is so high that everytime I alt+tab, the game tells me I just did 90000 in a second. Previously it was 1017 so the ring upgrade I got was probably what did it.
Are we over the 90000 jokes yet? Methinks not.
Back on topic, I think that heavy movement fights in equal gear and skill BLM followed closely by Bard. In an ideal environment, most probably MNK.
