Don't worry guys and gals. You hold the keys to this car.
If Dooku and Gunray are useful or even pseudo powerful, they won't release the direct counter for them or nerf their kits or the counter teams for them for at least two weeks unless the community somehow finds all the uses for the new kits, YouTubers share the information, and lots of the population gears them sooner.
Evidence:. Finn, Sith Assassin, Sith Marauder synergy with Darth Revan, Vader, Palpatine lead, Rebels, Malak patches, Anakin, Padmé, etc.
Don't star, gear, or use them for any game mode but territory battles and they should be just fine.
Use them exactly how CG wants you to and don't innovate, don't use other existing kits with them that are synergistic, and they should be safe until June when the next rework or release makes them 100% pointless.
PS :. There are several kits in game right now that these reworks will operate very well with if you look hard enough. Do not under any circumstances post about, make videos of, get excited for, or announce anything that cgs testers don't outright state in official posts and they won't get nerfed into Oblivion, or the squad counters for that matter.
Keep the information from easy access for CG employees and you'll be all set. Announce even one YouTube video showing something they didn't plan for and that's all she wrote though.
