Rogue Asn Spec, how do you feel about it?

[shadoh]

Hey everyone, i'm new around here but wanted to get some thoughts on how some better players feel about the Asn spec for MoP.

I've been playing a sub rogue wince Vanilla, love the way it plays, leveled with it, pvp with it, etc.. Finally came back at the end of cata with a friend who only raided, i've never raided before. So here i am slowly swapping my Ruthless pvp gear for PVE stuff. I've been playing sub getting 17-20k DPS in LFR DS, not used to the PVE rotation and what not, so i decided to swap to Asn, and use a geared rogue friends advice. Turned my 17-20k DPS into 55-65k DPS. I'm loving this Asn spec, how do the rest of you feel about it? Very very easy to play thats the only draw back i see.
