3.1 do nerf PHD significantly, so we will never know how Koreans would have performed against the elite WOTLK comps in 3.0.9.  Kill EA chose to withdraw from the tournament for a reason, those Korean teams were not exactly cruising through their own BGs as RMP. It is too bad Kill EA did not check the armory of their opponents, and realize none of the TWO WOTLK comps there had full time hunters about cheap wow gold.

So before you spec shadow dance on live, get on PTR, spec mutilate for your primary, shadow dance as your secondary, go up against any discipline priest in full PVP gear (expose armor nerf makes this match-up much much harder). You only need to learn the ambush/evis part of shadow dance to duel priests as it, so just swap backstab for ambush on your hot new shadow dance bar and all other buttons stay the same about cheap wow gold

Go try it, I did, and I was surprised how much more damage mutilate did with 66% wound poison application rate and 55 energy mutilate glyph. I will say shadow dance is superior for RMP, killing spree may be superior for certain 2v2 rogue/healer set-ups, but in term of overall versatility (and accessibility), the community favorite on SK-100 will still be 41/5/25, barring another major subtlety change down the road to get cheap wow gold.

I was really excited about this glyphs potential PVP applications, but even with deadly poisons 12% AP coefficient (up from 8%), it is still 30% chance to proc on a 1.4 dagger compared to wound poisons 66% on a 1.8 dagger. To really take advantage of envenom you probably need to put points into improved poisons. And you will probably need a warlock team as you will not be able to reliably blind your primary target and swap to get cheap wow gold
