(Took me waaaay too long to figure out which dungeon ARF was lol.)
Id actually semi agree, though when I last did it, was back in 3.0, and I was severely undergeared.
I also did unleash instead of A.D. Which is probably why I got through it with less power slashes.

Looking back, I could see myself using some more unleashes (instead of power slash. If i had to pick between more power slashes on trash pulls, or unleash in place of AD, i'd pick unleash for DPS for the higher threat/DPS throughout.)
