Yeah it's a work in progress, as you noticed. We are playing a Beta version of the game though, and they probably want to fix the big bugs and balance issues before potentially introducing more through revamping the artifacts system.

I could be mistaken but I feel that some of the common artifacts I got WERE through the steal the Orokin artifact missions, but if you get a duplicate it desn't show in the rewards.

I'd disagree that the bonus is minimal or not useful though. Energy Siphon allowed me to Link/Energy Vampire tank Lech Kril 2/3 of the time before I even had Focus or Streamline on my Trinity, and Rejuvenation just proved its worth in a 2-man fight against Vay Hek with a lvl 28 warframe.
