Conquest - Enemies are invulnerable/won't die
In conquest 3 I cannot beat bad batch. It keeps going to low health and they are invulnerable.
If you have the training droid Datadisk equipped, remove it.
The disk is not meant to make it more challenging, it is meant to make getting certain feats easier because the enemies won't die, you can repeatedly use abilities to get the required buffs and debuffs in a few battles. Frankly, I think it is a great addition, but only when used as intended.
It certainly does make feats requiring you to win X number of battles or win with specific characters easier but that was not why the disk was designed. Remove the disk, clear all 5 sectors, then put the disk on and go back and clean up your remaining feats
