You can't judge anything about his gear based on an idle shot. Considering he is using Windower, it is entirely possible he has plugins like BlinkMeNot (prevents blinking) and Silence (remove gear swaps from chat log) running.
My question is why are you nitpicking his "full AF" when you should be nitpicking over non-optimal idle gear (where's that Vermy?). Mages don't (or shouldn't) idle in their casting gear. But you already knew that, right?
And guys. Look at the log. He just killed the rabbit. So you're not seeing his idle gear at all. Give him a break. He just wanted to show how much exp a BLM can get from soloing in Bibiki Bay. =)
Maverick: AF coat for nukes? Why? No int, no m.acc, no MAB, and he's solo so -enmity isn't an issue. Cobra Unit Coat or anything else with +int will out-perform AF body.
