So I got on the PTR today on my 80 (geared) rogue.
Recuperate with no talents other than Quickening was ticking for ~1020.
Mutilate is pretty weird with some of the talents in the tree (still undecided about Venomous Wounds, keeping a Rupture up isn't THAT hard, but it's weird), but overall it's pretty ridiculous.
Oh, and even though all your gems/enchants etc are switched to Agi, expect to lose like 2% crit.
Vendetta is fricking amazing. It can't be dispelled, it's glyph (which no one has) increases the duration by 20% (:30 duration becomes :36), and you hit like a goddamn truck with it up. I was spamming 14k Envenoms with 4400 AP.
Also, I have glyph info:
You get 3 glyphs of 3 types, for those not paying attention. Prime, Major, and Minor.
Prime are for class-defining abilities like Vendetta, Shadowdance, etc.
The Primes are: Evis (+10% crit), Mutilate (-5e), AR (+:05 duration), BS (crits return 5e), Hemo (40% of damage is done as additional bleed), Killing Spree (+10% bonus damage), Revealing Strike (bonus to finishers increased by 10%), Rupture (+:04 duration), ShD (+:02 duration), SS (20% chance to add a second CP on use), SnD (+:03 duration), Vendetta (20% increased duration).
Majors are modifications to our major abilities like Sprint, CloS, etc.
Majors are: Sprint (extra 30% movement speed in Sprint), Ambush (+5 yard range), Blade Flurry (reduces penalty to energy generation while active by 50%), Blind (removes ALL damage over time effects from the target), CloS (take 40% less physical damage while active), Crippling Poison (+20% application chance), Deadly Throw (+20% to snare), Evasion (+:05 duration), Expose Armor (+:12 duration), FoK (+50% radius), Feint (-20e), Garrote (+:02 duration on the silence), Gouge (don't need to be in front), Kick (increases cooldown by :04, but if you interrupt something, reduces the cooldown by :06), Prep (renews Kick, Dismantle, Smoke Bomb), Sap (+:80 duration on non-players), TotT (removes energy cost, but reduces damage bonus by 5%), Vanish (increases duration of effect by :02).
Minors are cosmetic changes and very minor bonuses.
Minors include: Blurred Speed (Sprint lets you run on water), Poisons (apply poisons to your weapons 50% faster), Safe Fall (increases the distance Safe Fall allows you to fall without taking damage), Distract (+5 yard range), Pick Lock (+5 yard range), Pick Pocket (+5 yard range).
Basically, glyphs for PvP look sick.
Obviously for a Mutilate build you're going to take Mutilate, Vendetta, and Rupture/Evis (depends on if Evis glyph works for Envenom) for Primes, Sprint, Blind, and Evasion for Majors, and Blurred Speed and whatever the hell else you want for Minors.
That was a lot to type out, but I wanted them all in one place so that they're easy to read.
Oh, and also, you learn a glyph once and then you can always use it, but to overwrite a glyph, you need Vanishing Powder. No idea on where you get it, but I'm assuming it'll be common and cheap.
