In group and fighting, I'm 100% Tiger Stance, with the exception of when it fades (fortunally easy to spot as critrate drops back to nothing ;p).

Eagle Claw < always start with it. If there's two other AC debuffers (15% removes nearly all mitigation of virtually all mobs, a second AC debuff clears of all) in the group, I'm not really bothering - I only use it as a Jin supply when nothing else is availible.
Cresent Kick < Use whenever up. The critrate of Kicks along with Tiger stance makes it a stellar Finisher provoker. Since it's currently out of the global cooldown, it dosen't stop endurance regen nor stop autoattack.
Ashen Hand < Spam whenever sufficent endurance. With two-hander, it outperforms flying kick in all ways (except on skeletons).
Iron Hands < Use when fights are exciting enough to pay attention. The one minute duration makes it easy to slip up on when it starts going into a grind.
Secret of Flames/Ice < Like Iron Hands. Even with the upped effect rate, I'm not really noticing anything on Ice III (proced stun 4 times in total when using it - but it appears others are having better luck with it) and Fire V (never proced the DoT at all) - presumably the chance got upped by 8% or something.

At any time a counter pops (due to agro) I activate it (since dealing weapon damage, they actually deal an impressive amout of damage with a 2hander and trigger from G pressing aswell, very neat!) - if a finisher chain goes off I go for it. If I'm currently blank (cooldowns, lack of Jin) I'll just use Eagle Claw due to it's low endurance to refresh the AC debuff which usually results in having Ashen Hand up or provoking a finisher (which resupplies Jin nicely).
If there's a bear-shaman/cleric in group, it's a virtual non-stop ability spam, if not, it does require some timing to get most effect from it.

If fights aren't to snoozy, I'll use Jin Surge. Hmm, even if they are snoozy, I'll use them if nothing else to let the psionist die some.

I still always use the jin surge / feet of the fire dragon combo. Specially against 3dots even mobs it's a great addition.
At lvl 31 (with ok- not uber stats and gear) I hit around 300 average and 774 being the mix so far).
