This is for the unit and the faction. Now, I know the faction will not be in the game as a normal faction, that's been made clear. I'll get to that in a moment. What I am unclear on is the soviet Yuri unit/psicorps trooper. the FAQ on moddb says the unit will be in the game. However, a dev (forget who) said about a year ago in a match the unit and mind control as a whole won't be present. Which is it, and how will the unit work in-game if it is in?
As for the army, It's perfectly understandable they won't be a full faction. However, What about special Co-op matches or crate drops (virus sniper rifle anyone?)? Some of the relatively "easy" Yuri stuff like gatling guns, initiates, non-functional base structures, and maybe even their own engineers/technicians, while leaving the difficult stuff like psychic towers and chaos tech out of the equation. That way, you can still have Yuri without a need for balancing and coding the hard abilities his forces possess.
Keep in mind I'm just thorwing out ideas. No one's demanding this be done. Sometimes I get yelled at for far-fetched ideas, hehe.
