Anyone have tips for winning as the CIS when assaulting the planet?

I do alright taking planets up till the Republic get Sabertanks. Then i can even get out of my spawn. Dooku does a great job soaking damage while i try to bring in something with with my 2 free population >.>

If i try to build Anti-Vehicle turrets they get focused down before they are even built. I tried Homing Droids with Repair points but the repair points get torn down and then the Homing Droids get disassembled by the endless wave of Sabertanks.

Also whats the best way to deal with Jedis? I legit lost something like 25 Droideka, 100+ Battledroids, 10+ Homing Droids and Dooku, Ventress, Sing. As well as countless other ground units to just Anakin and Yoda on a planet.
