Best Nightsister counter

Imperial Troopers and Bounty Hunters are my two that I use the most, Sith Triumvirate is what I turn to if I'm out modded/geared to the point where the other two won't cut it. Separatist droids are also great. Two key aspects to beating the Nightsisters you either need to prevent revives, have great AOE damage, or both. Troopers once the TM train is rolling will outspeed them with TM gain and have great damage and several AOEs to knock down the sisters. BH with Jango and Boba have two that can prevent revives, and have decent AOE. Sith Triumvirate should be pretty self explanatory. Separatist droids is more like the troopers...just power through with AOE damage from B1 and grievous, and B2 had buff immunity for zombie (can also use tech from wat to prevent revives, for any character on any team).
