So here is the squad that I used...
Chirpa (L) G9
Teebo G11
Elder G10
Scout G8
Paploo G7
Mods are not optimized but I do have +30 Speed mods on all but Scout. There are a couple of keys that I use when playing this. First, for battles with the AT-ST active, I only attack it. Seems obvious but figured I'd state it. Second, I also tend to kill the Healing Trooper first to avoid the heals. Third, if the AT-ST is not attackable, I tend to hold back CC's buffs until after its first attack since it defuffs everyone.
Otherwise, use TM reduction when you can for Teebo when stealthed, and use Paploo & Teebo for debuffs. I tend to focus on one toon at a time given the weak damage that the little bears cause, with Elder debuffing/healing, and reviving toons as needed.
This works pretty well but not 100% of the time. I probably end up winning 3 out of 4 tries. Hope this helps!
