I'm not sure Tuanha, but I don't see the reason for Kidney Shot someone out of burst mode. I'm aware of the fact rogues need to stunlock rather than do pure damage, but a timed kidney shot while dancing (or better: an instant BEFORE) is far more better imho; I personally don't want to have kidney shot on cooldown while dancing.
My go for a good opener (according to the arena junkies article you posted) would be: garrote/cheap shot with shadowblades up, using subterfuge to make a mini-shadowdance effect and to apply pressure on the opponent at the very beginning (it's not the actual burst but it might lead someone to pop some defensive CD), keep it up with backstab and eviscerate/rupture, then Kidney shot and push with the real dance with a fair amount of energy (I want to be able to push 2 ambushes) when I'm quite sure I can land the kill. At that point I want to make sure I can rely on kidney shot. If I'm confident enough and I could put the guy in bad shape, I could even dance after subterfuge on the opener and, in that case, I would shadoblade while dancing in order to have the maxium burst potential I can. In either case, having a nice kidney shot while bursting is pretty much mandatory I think. You'll never be able to kill outside SD (at least you're lucky enough with the help of your partner); what you can do is set everything up to dance effectively afterwards, wich means most of the time "end of the line, pal". As sub, seeing your dancing getting screwed up is damn frustrating and that's exactly what your opponents want.
Ok, you're not that good out of SD. But if you pool your energy to 100% or so, kidney shot and dancing with Mark, man, a few can whitstand what you're about to do. You can even vanish offensively and SD two times!
That said, it's good to land a KS and then trick your partner, but that should be while pooling energy and waiting for your dance to reset, if for some reason you weren't able to kill the target.
Expecially with this patch, sub rogues gives that kind of "make it or break it" feel. But in generall, I think Blizz have been translating The Rogue image very well in terms of mechanics: wait for the right moment, find the weakness, then do the job.
I'll repost the article if someone wants to have a look at it. I think it's great.
