So, use the Teth Monastery map (or a different one if you want) There are two teams, Good vs. Bad. These were the teams I used

Good: GOWK, General Skywalker, Commander Cody, Captain Rex, 501st Commander.

Bad: (1. 4 Battle Droids, 1 Security Battle Droid, 2 Heavy Super Battle Droids, 1 super Battle Droid, 1 Super Battle Droid Commander, 1 Battle droid Sniper)
(2. 3 Commando Droids, 1 Commando Droid Captain)
(3. Asajj Ventress Sep Assassin, 2 Magna Guard Artillerists)


So the Seps come in waves, the army first of droids first, then the Commando Droids, then Asajj and her Magna Guard Artillerists. The second wave of Droids, (the Commandos) come in to the map once or if the droids are defeated by the Jedi or The two clones. The third wave ( Asajj + Magna Guard Artillerists). The Jedi and Clones can move simultaneously, and I call it "linked". Rex is linked to Anakin, and Cody is linked to General Obi Wan Kenobi. So if you move any one light side charater their partner can move with them. I have playtested this, and it worked well. The droids, (me) barely lost as General Skywalker was making great Missles Saves. General Skywalker was the only survivor at the end. Post here if you have any questions or you wanted to tell if you playtested it. Also, you could probably change up the teams, but I found these teams to be very equal.

We didnt use the errata, we used what waas on the card. yes, gowk got defeated. really.

I like the scenario of waves of attackers - much more like the movies and TV show. Not always the best military strategy, but looks good on film. I like how you have adapted that for these teams that looks pretty balanced on paper. Good idea.

Yeah, I find GOWK easy to kill with Dooku of Serreno. Against melee it is Dooku that seems impossible to defeat. Once he took out GOWK, Anakin Jedi and Commander Ahsoka, he only had 20 HP left but he survived.
