Just my two cents from my experience today.

I qued for the Ultros fight. It was my first time as I'm just now catching up on the Hildy quests. Before I could type anything one of the tanks spat out "Which dps is new." I explained that I was but I had looked over a guide.

Part of the way through the fight one of the healers throws out this piece of gold "Lol noob you didn't read a guide"

Now maybe its me but reading doesn't mean I'm going to get it right the first try. Nor was I the only one being knocked out of the arena. There were no wipes, no deaths, no close calls. Until that point I'd thought it was an extremely smooth run. The only issue seemed to be that I was on SMN and new.
