For the most part, the 33/38/0 Fan of Knives build is extremely limited in scope. Even in 5v5, where the spec is supposed to shine, all it takes is a few rounds before most team figures out a way to deal with this spec about Wow Gold.

Maybe when it will not replace 41/5/25 as the definitive rogue PVP spec, Reckful 5/54/12 is definitely one of the most innovative specs around. You give up deadly brew (and as a result, will not be able to double wound) vs 33/38, but you pick up 1 minute cloak, ability to actually sap someone thanks to the stealth talents, prey on the weak to counter resilience damage reduction, and more importantly, killing spree about wow gold. Once you pop adrenaline rush and starts spamming fan of knives, people are going to want to move out of the way. That is when you get to killing spree for a nasty surprise when teams want to "leave the FOKing rogue alone". I still believe killing spree would be rogues best PVP spec if it always does single target damage that the only reason I can not play it effectively in anything more than 2v2 is because it is almost impossible to land it cleanly in larger brackets. With FOK teams will be forced to leave you alone, gives you the perfect opportunity to do full damage about Wow Gold.

A level 70 rogue will have 400-500 agility easily, 75 agility is a healthy buff, especially with the new mongoose enchant (chance to proc +120 agility), paladin blessing of the kings, and shaman grace of air totems. Deep subtlety rogue scales extremely well to get more wow gold
