Basically, we got two things: Tactical Sense on Suryat HMG. The Suryats were really struggling to find a place in the sectorial, imho, and this might a solo Suryat HMG more viable, and give an otherwise-elite Onyx force some more order economy. Then, of course, we have the Rodok changes. The KHD isn't so big a deal, since we already have such good KHD options, including Kerr-Nau who can be in the Rodok fireteam, but if you're running a Rodok Haris it might be a good fit. And that's the big deal - a Haris fireteam that doesn't cost 160 points. It's not as flexible as the Rodok core, but a smaller model-count fireteam is easier to move around in clever ways that take advantage of super-jump, and could definitely change things up.
