Christ, the rogue review is hot. Pretty much seems like they got rid of a bunch of crap talents and added nicer ones. Subtlety tree looks a lot nicer, though not nice enough for me to take it. I'm sticking with Seal Fate as of now, but I like where the new talents let me get some points:
I like the improved Feint. I feel like using AR in raiding would pull aggro a LOT. I'm not sure about imp evis over SnD, either... I guess we'll see, eh?
Also, I put together this Subtlety build (stunlock): www.wowhead.com/?talent=j0eb0xZGZxbeoouRqo Take a look at Ghostly Strike: only 40 energy now. Worth using as often as possible, methinks. 'Course, with a stunlock build, you shouldn't need to dodge most of the time, eh?
And a Subtlety daggers build: www.wowhead.com/?talent=j0eb0bZGcZVbIs0GRVo The bummer with this one is that you can't get full Lethality. You do get the Armor Reduction talent and the Attack power bonus talent, however.
I really like the new Subtlety tree talents (Slight of Hand, Deadliness, Serrated Blades, Heightened Senses). Subtlety builds just got a lot stronger. Premeditation even, is a better talent now. No casting time, 2 min cooldown. Not too bad for PvP. Premed, Cheap Shot, 5 point finisher (Evis or KS). Nice. Hell, in MC you could premed then SnD immediately.
SF kicks a lot of ass, but its more of a hybrid spec in my eyes. It works well in every situation, but isn't the best at anything, except maybe 5 and 10 mans.
You can build a better PvP build, I'd like to look at some using a lot of subt like you are post 1.12, and I think the PvE build I made will max raid damage out.
As for Feint. . maybe its because I got Feint rank 5 from AQ, but I'm usually pretty good about managing my aggro when I want to. Granted, a lot of times I slack in that department, but when I'm paying attention, Feint already does what I need it to.
If I had the epic swords, I'd consider a hemo build, but I don't, and I'm not going to blue swords just to try it out. I like my daggers too much (even if I don't have Perdition's).
They say the truth will set you free, but they don't say how deep the cut will be.
I don't feel like there's enough you can get from subtlety by going any farther. Serrated Blades is nice, but you can only get 2 points in Deadliness. You do get Prep, however. Elusiveness may be worth it for reduced cooldowns on vanish and blind (stock up on powders). Overall, though, I feel like subtlety shines for stunlock builds.
Stunlock builds are great for dueling, but for World PvP (i.e. BGs), high burst damage is where it's at. You need to kill fast or you'll soon find yourself outnumbered. On a PvE server, BGs is about the only reliable PvP action we can get. Big hits net the wins here. You don't have time to stunlock an opponent to death in BGs.
For burst damage, you cannot beat the Assassination tree. Quick Combo Point generation with SF lets you KS or Evis your opponent into nothing. Cold Blood for free Evis Crits every 3 mins. Vigor lets you pull off combos that aren't possible with only 100 opening energy points. This is even better with the 5-piece NS bonus.
The combat tree is great for grinding and raiding. Its talents give you consistent, reliable sustained DPS. Lots of passive talents to enhance your natural abilities. Improved Kick and Riposte are great PvP skills, though. The new Improved Sprint is mighty tasty, as well. The combat PvP build I put together looks like this: www.wowhead.com/?talent=n0eboxZGcxzrLZV0xc
I think it's pretty solid, but I'm still going with my trusty SF. I do want to get myself on the Test Realms and give all these specs a shot, though.
I'd say for PvP Builds, SF is pretty strong. Especially for BGs. It's not the perfect raiding build or the perfect grinding build. As far as versatility goes, though, I'd say it's damn close. The only thing it can't do is maintain a reliable stunlock. I tried a Hemo stunlock build some time ago. While it does lock opponents down, it takes SO much longer to kill them. Safer, but slower. I'm about killing fast and hard. That's how I roll.
