Depends what you're running, I guess.
The rapier is a nice little dr breaker for non-GS alts.
The dagger is, frankly, what the epic Spy Dagger
should have been (minus the self curse): interesting debuff, a GS effect, plus Deception.
Even with the self curse, it's quite nice on a rogue when you don't need to beat DR...lot of synergies with crowd control and caster insta-kills.
The bow is pretty sweet (if I had someone who used longbows...)
The living armor looks pretty nifty...if it got something cool in the upgrade...off topic, but why do the new light armors seem to get the BS AC bumps while medium gets the goodies like resists, sfl, dr. etc?
