I’m finding that i use two core teams, with the ability to break JKL into his own when appropriate.
JKR, GMY, Bastila, Jolee + 1 (Ezra / Ben)
JML, Hermit, JKL, Shaak + 1 (I like Aayla for the whack-a-mole stuns, and she’s needed for JMK anyway)
As previously noted, if you don’t need the full-fat JML team, JKL with Hermit and Ben make a killer team themselves (fast Hermit to get things started). JML can then just use some leftovers and do all the damage with the Jedi’s Lesson special calls
(Note that this assumes that Ashoka, JKA, Kyle and GAS have better things do!)
