From my experience no one expects a SR in the Duty Finder.
AK has been dumb down since you last played and it is still a very easy run. Just pull each pack as you get to them. The mechanics are all still the same.
Going at a decent pace you'll finish the dungeon around 20 minutes or so if no one dies.

I don't think people really run AK much anymore unless they need it for Relic or some other quest. Haukke Manor HM is very good for farming since you get 50 Myth from it and it's an easy run with half way competent people.
