Mods for bad batch, dark trooper, bo-Katan?

Dark Trooper is all offense. I suggest offense/health sets, or offense/defense. Because of the way his kits works, he's kinda vulnerable to being focused out of the battle, so he likes some survivability. Offense primaries wherever you can squeeze them in, ideally, including an offense primary arrow with a high speed secondary. DT has high basic speed as well, so making him fast as well as hard-hitting is a good call. CC/CD is useless on him, he won't crit often (only with advantage and Troopers don't hand out that buff--in fact, I think only Dark Trooper does).
