It's nice to have features. We want to work little more on core features to make them right. We encountered some troubles when we try to extend functionality to our AI it takes lots of development time just to add simple things to AI and the main problem that we can't control AI decision cycles properly and debug those. That's why we decided to improve AI for 1.7 by making Node based User interface to control our AI. I believe we all benefit from that by having believable AI in our games.
