Rogue questions for Arkinia and Talias

[Shadowjack]

Has to do with a PvP talent build,

For most of my carrier I have been an assassin/combat build. Even after hitting 60 I stuck with this due to being able to do more damage in Instances and soloing. Since the Honor system has come out I have been thinking seriously about switching to an assassin/subtlety build. I have continued to stick with my combat build to accumulate more +attack power items in instances and improve my gear, while testing builds on the test server. I feel I have finally come up with my PvP build and would like some constructive criticism

This is my PvP build 21/2/28

Assassin talents: 21
Improved Eviscerate 3/3
Malice 5/5
Murder 2/2
Relentless Strikes
Lethality 5/5
Improved Instant poison 1/5
Cold Blood

Combat Talents: 2
Improved Sinister Strike 2/2

Subtlety Talents:
Master of Deception 5/5
Opportunity 5/5
Elusiveness 5/5
Improved Ambush 3/3
Initiative 5/5
Improved Sap 3/3
Preparation
Hemorrhage

I have also thought about substituting Elusiveness and Hemorrhage with Improved Gouge 3/3 and Improved Backstab 3/3.

My attack pattern would be as follows.
Cold blood, ambush, hemorrhage, blind, vanish/re-stealth, preparation, Sap if needed, ambush, cold blood, eviscerate (4-5 points), vanish, sprint.

Suggestions, your thoughts?

Any build is only as good as the Rogue that uses it. Go with what you like and what you know how to use~
