I'm fine with SnD for sub, with talents keeping it up most of the time and occasional refreshes when necessary, the 50% attack speeds also help remove some of the sluggish combat, makes playing WoW more enjoyable for me.
I haven't tried Assa and a bit torn on outlaw, but as long as I don't have to waste time and combo points on roll the bones, the (in my opinion) worst ability they've ever designed for rogues(maybe entire game).
Were you would constantly reroll effectively giving it, what was it? about a 40% miss rate? ..it felt awful even if the end result was good.
