Agility: 4.74
Hit: 3.13 to soft cap, 0.75 after (or ~1.42 throughout*)
Expertise: 2 to soft cap (or 1 throughout*)
Mastery: 1.95
Strength: 1.8
Haste: 1.75
AP: 1.71
Crit: 1.7
For PvP, the value of Hit goes down to ~1.07 throughout*, Expertise to 0.4 throughout*, PvP Resilience is 4.73 and PvP Power 4.72. Haste is the second best secondary stat, so if anything, get out of Crit into Haste (given a Mastery/Crit item).
Assassination clearly uses more than 3 buttons.
Unless you have a Guardian Druid in your party/raid that really wants Mangle all the time, then you're the next-best person to put up Weakened Armor with Glyphed Expose Armor.
*I'm using these values in Pawn for my character, as there is potential benefit (and loss) in being not Hit- and not Expertise-capped: a missed Envenom deals no damage but grants you the Envenom buff, whilst also costing you no combo points. This makes chain-Envenoming slightly easier, but is offset by Dispatch procs missing (as they are consumed even if they miss and they don't grant a combo point).
