One saved his life from you killing him.
Two made it possiable to kill you.

You could argue the - Your flurry killed you. It was a 50 50 - with out his first legcays it would have been coin toss your way.
You could argue that - You flurrying after hamstring art (possiable hurl) was a bad idea.
Boneshatter = not anything to consider on his set is race and his powers.
Ham and Art on you hurts. Less your geared alot better then you have been.

His conceal edges helped a ton not to mention signal and dagger specs powers and other edges and so on.
You also not prepping helped him win that.

STSF just adds to this all.

Trust me, I hate the whole Dex movement, more then anyone ever.
But this was not STSF that got you. - It helped - but so did everything else.
