Heres how i look at it... Unless your having problems surviving... Which most archers arent at all.. then pick up anything that bumps up your dps..

Applying Break Armor 5/5 while focused and doing a blast shot yields 1 hit kills to the broken target alot... Not to mention on bosses is a nice debuff that helps the entire party kill him faster. So I would say currently its worth the points.

Also I tried out the dagger/wingshield... VERY NICE!!... See.. I assumed blast shot wouldnt work unless you had a ranged weapon equipped.. But not true.. In fact I noticed ranged specials are still ranged and your weapon only affects your primary attack button.

So right now I'm rocking wingshield / sai dagger ... Auto-Crossbow..

Also.. This will probably get nerfed eventually but I'm wearing epic warrior armor.. by stating str... equipping it then respeccing leaving the armor on.
