Anyway, this is the build that I seem to have the most success with, but I'm looking for tips to improve it, or even give me a better build (however drastic, don't worry...I won't flip out if you post "elitist" comments either

R/W
Attributes:
13 expertise (10 + sup rune)
14 wilderness survival (12 + mask + minor rune)
9 marksmanship (8 + minor rune)
Skills:
Distract shot
Choking gas
Practiced Stance {E}
Frenzy
Whirling defense
Favorable Winds
Troll Unguent
Rez Sig
Gear:
Ebon PvP Short Bow of Fortitude
Druid's armor set (let's face it, the others suck)
So you can see the basic idea, keep choking gas up all the time by using practiced stance, and target a spellcaster. Simply using Warrior secondary for frenzy for more constant interruption without needing any attribute points. Whirling and troll unguent to keep me alive (it's random arenas, and even if I get a monk it's nice to not put any more pressure on him). Troll unguent is healing me for 200 HP over 10 seconds, not too shabby. Distract shot is for interrupting skills instead of spells, most importantly rez sigs. Favorable winds is for faster arrow speed, so I think that will help choking gas interrupt better? Not really sure if I need it, but I put it down when my team has as many or more rangers than theirs.
Frenzy doesn't seem bad at all, because the only real damage I'm looking at taking is from rangers and warriors (I'll be interrupting eles too much), so I just stance cancel to whirling defense (which I would have done anyway) when they start attacking me.
13 expertise is a nice breakpoint for all those 5 and 15 energy skills, and it's linked to whirling and practiced stance. Wilderness survival as high as possible for a long choking gas. Marksmanship at the minimum for using the bow.
For my bow, I don't see how any of the upgrades would really help my build, so I just went with earth damage and 30 extra HP

I really like when there's an ele on the opposing team, I can really shut them down with the CG. Mesmers and Necros are also really fun to shut down. I find that monks are harder....their heal skills fire off so quickly that if choking gas isn't perfectly in sync to screw them up, it usually misses. The new distract shot is nice though, I can actually pick off orisons now.
I've really tried to fix builds to use incendiary to deal some actual damage, but I just come up with too much downtime even with serpents, without using QZ (which I'm not about to bring and piss off my teammates). I've tried going the damage route, using conjure lines or mark of rodgort + kindle, but it just doesn't seem to work consistantly and I usually have energy problems. So, any tips for me?
(after looking at my attribute setup, it looks like I didn't optimize it....Can someone confirm that? I'm just used to always going for the 13 expertise breakpoint with a sup rune.)
