Can't beat light side JKR + Bastilla with my Empire squad

Well, from my experience, it's a bad idea to go with such an Empire team against JKR.

Vader being the fastest and opening with Force Crush (starting the imperial TM train) is rendered impossible with JKR's auto-tenacity up.

From there, you then fight an uphill battle, hoping you're lucky enough for a nicely timed AoE debuff (mostly by BSF/Vader).
