You got Impulse Rush, actually! That's an even better haul. I cede the point that it can be powerful in the right circumstances, but I contend that it's way more powerful in isolation - in a larger fight, they'd have garbage buffs (like e4e, regen, or medica II) that reduce your odds of hitting something primo.

A high end result like that can definitely help you survive, though, but for that particular clip I would have taken the odds for your survival regardless! Two DPS, even good ones, really isn't enough to finish off an Astrologian.

And, hey if we're linking winrates: XIVPVP has me at 57.82% lifetime, and i'm at 73% for the week :P
