To me the OSS looks like half-cooked. I've been trying to make a list I feel comfortable with, but it's simply... like having a huge menu but being forced to have a single dish. For example, there is a single option when it comes to Haris: Shakti with something, which can be an Asura and 1-2 Yadus or Rudras. When it comes to Cores... Dakinis with Samekh only and the Apsaras (which is kinda Puppetactic, and it's not bad, but could use better wording) but you can't really go LI with this, since no engineers link in a faction more about chrome than flesh... And you have 2 options only (Sophie and Mk1... which can be medic or engineer only), which are also the medic option. Not having NCO released when it was sold as the next best thing to go with the Asura Lt2 (available only in the sectorial), the Yadus not going with Dakinis... sigh...
Eh, I feel like NCO should be distributed to all armies or not at all. It feels weird when only given to one faction; other factions have NCOs, after all.
Yeah and not yeah, the same way Chain of Command represents someone who "oversees the strategical situation" to take over if the Lt falls from the control "seat", the NCO might be the representation of someone staying on top of things to take advantage of stuff. Anyway, at 2SWC the NCO is what sells or kills the Yadu HMG. Her points costs is already too close to the Dakini HMG :/
NCO rule will be added to the rules pdf & wiki with the next "new rules" document in the coming future. You'll be properly informed about the update.
