Assassin Arcane archer build help

[Arovin]

I posted this a couple of weeks ago in the rogue and wizard forums but got no feedback. I have been constantly making adjustments to the build and this is what it has evolved to now.

I am hoping to use sneak attacks from range (I know 30 feet is not very far in DDO) as my main source of damage and my spells mainly as buffs and CC. I went Way of the Assassin for extra damage and because of the upcoming improvements in the next module. I am hoping that with items my DD and OL will be enough to get by.

What are your opinions on this build?
Thank You.
