Shaolin stance is safe as f**** if you go for the low kick. If you go for the mid/OH "combo" and you try to use it as a range attack you are going to eat a punish. But if you do it in a good range its okay.
But Shaolin Stance is very useful. At low and mid level play have great use, and its a 50/50, because opponent are not that good on reaction.
At high level play, low kick is very useful and its 100% safe, and its insanely fast.
