I need an opinion

What do you think about the build below? It is focused around Blade Flurry with two swords.

I'm aware that I may not reach the level cap but I prefer to plan ahead. How viable do you think it is in high tier maps? Is there something I should change? I am a SC player.

Well, it is bad. Honestly :) You take a lot of weak nodes (compare Master of Force and Born to Fight) and don't really get any serious support from your ascendancy. Taking these nodes as a Scion is twice as bad.

Here is an example tree:

As you can see, I utilize the ascendancy to get very strong crit and sword crit clusters. In this case Scion makes at least SOME sense. This build can't really compete with Occultist/Assassin/Raider, as we have no reliable sources for charges. But it should be more or less playable.
