Need You help to refine my list

First and foremost, I see nothing inherently wrong with your list. You need experience in handling it and with experience will also come your own preferences.

Infinity is sufficiently complex and sufficiently closely balanced that we can't "refine" your list without also infecting it with what works in our meta and with our own foibles.

I do see a question that needs asking.

With Sun Tze, the major advantage is being able to push a group beyond 10 orders, but how are you planning on handling the Kuang Shi of whom 2 won't be in a link?

Other than that - just play more!
The list is good. Try and find out what rules mistakes you make, where you place models wrong and where your friends' blind spots are to exploit.

 

I love Sun Tze BSG, he's amazing as a DT and in missions where you have to control zones and have army points just standing there. I'm also a fan of two combat groups with the Su Jian and the Rui Shi taking point.

My advice, since you have SWC to spare, is to put 1 KSCD + 4 KS in each group, then round it up with specialists and a big attack piece. Also, try the Spitfire version of Suji, she's pretty good. If you are putting the Rui Shi in group A, remember to put the HD that's gonna buff it in group B, so as to get max amount of orders to rampage with it, same concept applies to the link team deploying smoke. And embrace Ninjas, they are awesome. Maybe something like this?:

You can easily drop the Ninja and put the Spitfire Garuda in there as well, you can pay the SWC.

Hope it helps!

 

You can use Sun Tze as an ARO piece, as well as the Warcor. Sunny has 17 WIP to throw those nice Pulses. The Warcor and Flashbot are not that hot, but they are pretty disposable IMO. My personal prefference when playing ISS is to forgo dedicated ARO pieces since you have really nice DZ defense with all 8 Kuang Shi. Of course I'm not saying is the best, it's just how feel confident playing.

Regarding free-Kuang Shi, I try to put them in total cover, in a place where they can just move 4 inches along the wall and stay in total cover (if possible) or way back the table, behind tall buildings. IMO they are so cheap that even if killed they pay for themselves since you get the orders for that turn anyway. Just remember you can cancel their impetuous mov with regular orders (canceling everything may not be worth it, but you can afford to spend one or two to save a couple of guys that would be running towards certain death).

Those are my two cents.

 

Yes, Strategos shifting the LT order is what I mean.

As for the Kuang Shi, loose Kuang Shi have a nasty tendency to evaporate during the first game round. That's what you need to deal with :)
Setting up for order redundancy is good and all, but there's a risk of a small order draught here.

 

There is no such thing as an all comers list or silver bullet in Infinity. You will know your missions before hand. Tailor your lists to better suit the missions, that is part of the game.
