So I thought I'd put up the PvP build I've been using to great effect, having used it for nearly a week now. 3/2/31
The #1 thing is that this build hits HARD. I'm getting 8k ambushes on resil, 5-6k BSs on resil.
Lack of Waylay still bothers me, but mostly due to me ganking people off mounts in WG or BGs. Glyph of Crippling Poison solves this, as even with dispels up, Crip procs nearly instantly after it gets dispelled (assuming 1.4 or 1.5 speed OH).
Another thing: mongoose is officially the best weapon enchant again, regardless of what spec, and regardless of PvE/PvP. That haste increases energy regen and Agi:AP is now 1:2 (similar to hunters) means that it's an incredible enchant, and procs much more often than Berserking.
Imp Recuperate is a MUST in EVERY PvP build. EVERY SINGLE ONE. 5% HP every 3 secs in addition to 6% reduced damage while it's up is absolutely priceless and by far the best talent we can take in PvP for our splash talents (talents that overflow into other trees). No joke, when I first specced into it and tried it in a BG, I could have jumped up and danced, I was so excited. It gives you that much survivability.
At 85, this
will absolutely, 100% be the best solo PvP spec out there.
That said, variations do exist, and they're pretty gear-dependent. If you have massive amounts of haste, reforge/re-gem haste (i.e. agi/haste red, haste yellow, hit blue for damage socket bonuses), spec this
and have a blast.
Some things NOT to do: reforge mastery. It's a complete waste for PvP. You'd need to be in a 15 person raid with crits going off literally every second for it to be worthwhile so you could spam Evis and keeping up Rupture. Without the crits, you'd be worthless.
Reforge crit or hit as needed. I'm personally up to 45% crit after reforging away hit so I'm down to 5.1%.
For poisons, I tend to use Wound/Crip/Mind-Numbing on MH/OH/thrown. Because procs are so frequent from FoK and Deadly Throw, if a mage or warlock gets range on you, feel free to toss a Deadly Throw at him to slow down his casting. Obviously, you're going DP/WP/MN for mutilate.
Glyphs that are absolute MUSTS for Sub: BS, ShD, Garrote (must for ALL PvP specs), Sprint, Crip (if you don't pick up Waylay).
That's pretty much what I've found thus far. Oh! And use my trick to regen some health in stealth: Premed then sap, use CS but don't hit them so you have 5 combo points, stealth and Recuperate for ~50% of your HP back. It also works if they're spamming AoE: premed, recuperate, repeat (as premed is on 15 sec cooldown).
Remember, slow/fast for pretty much every spec (since DWS isn't available to mut or sub anymore).
