Combat build critique

[Gurnsey]

I haven't run into a melee weapon yet that can't have poisons applied to it.

Since this is the case, the final determination becomes:

Does the added damage that daggers add from poisons (due to their faster attack speed) balance the lower SS damage damage (from lower damage range)? If so, does the increase in SS crit damage from Dagger Spec beat out both the (possibly) lower dps from daggers, as well as the extra attacks from sword spec?

Like I said, complicated.
