I'm a DW+Bow Sorc myself. This looks like a decent enough questing build, but it wouldn't be terribly viable for end-game. There are a few issues to consider.

The first is resource management. If you want to do good damage with dual wielding, you'll need really high stamina. It's unlikely that you'll have enough magicka, magicka regen, or spell cost reduction to consistently use Streak, much less to use it alongside Surge and Shattering Prison.

The other big issue is that Ruffian won't come into play against bosses or players. Bosses generally can't be CCed in a way that would allow you to take advantage of Ruffian, and players will break the CCs too quickly to get any real benefit. You're really only going to be looking at basic damage. That said, you could be highly effective when assaulting keeps. When inside close quarters like towers and keeps, it is very difficult to escape Absorption Field and Ruffian *would* come into play. Using Surge and Steel Tornado you could do a ton of damage to the enemy. Combine this with the built-in execute power of Steel Tornado *and* the Slaughter passive, and you'll dissolve the enemy forces.

It might be more useful to focus simply on reliable damage output and blocking/interrupting and subsequent knockdowns, and use your spells for utility and defenses rather than proactively.


Regarding Bow abilities, Snipe is your powerful move (especially since multiple arrows can be flying towards the target at one time), Poison Arrow is a great supplement to that, and either Bombard or Magnum Shot will be your best bet for kiting, depending on the situation.
