The Star Viper really isn't that bad a place. It's a touch overcosted but not horribly. I've had moderate success putting a couple 25 point Black Sun Enforcers into lists paired with Boba or an IG. Honestly I think the addition of the Khiraxz is going to help the Star Viper as its going to open up a lot of room for list building in the faction.
The one and only thing that is in dire need of help is the Scyck and at this juncture I have zero expectations of ever getting a Scum Aces pack. There are a ton of options that will be available to Scum players 9 months from now when we have all of the new stuff from waves 7 and 8 in play.
I think it's much more likely that we are just stuck with a dud ship for a long time. Perhaps an opportunity will come up for a fix elsewhere. I just can't see a Scum Aces pack being a big seller just to fix the Scyck and give something else that's already good more options.
It's fun to theorized but FFG needs something that will sell and the Scyck's will struggle to sell Aces packs.
