AC Seeming to have little to no impact

[Throndor]

Send me a tell if u catch me on this weekend. I can hop over to test with a beta buffed cleric, and my chanter to slow and extend the window which u can keep your tank's propped up if u want a prolonged test.
For the sake of consistency, you probably shouldn't even kill the mob your using to parse, and just camp or blur the mob between parses, although maintaining agro without dmg may be a bit problematic with a warrior/monk.
