15/0/5 Dagger Spec?Follow

Is this a good skill point setup for the BG's?

Assassination
2/2 Remorseless Attacks
5/5 Malice
3/3 Imp. Backstab
5/5 Lethality

Subtlety
5/5 Opportunity

I'm thinking about respecing to this since I've got 2 Torturing Pokers with +5 striking on mainhand and Lifestealing in offhand.

Give me some input and advice please?
