That wasn't because of single target damage. That was because you could cloak every phase and stay in the whole time. Morchok was also stupidly easy which probably caused a lot of people not to care enough to bother. It was strong at the end of t12, but above combat? I don't think so. And again, no'kaled was insanely strong. What were your dagger options during the time period before the first guilds went 8/8? A 403 off dw with no proc, 397 p1 daggers, 410 fast dagger off of hag. No'kaled was way, way better than those for combat.
