CLS leadership zeta grants TM when a debuff is resisted.
3PAC assists every turn and has a debuff on basic. CLS has 2 debuffs on basic, etc. When 3PAC's turn comes up, he goes for the AoE blind & if they're all resisted, that's a whole lot more TM, keeping the train going.
The assists will produce extra Protection on GK (when taunting) or other toon targeted, but since you're always resisting debuffs they keep taking turns and the occasional AoE will wear the other toons down. If they aren't targeting Padme, there are no assists to give her Protection, and the AoEs whittle her down & she dies.
Then the bonus protection stops (from her unique) but the auto-resist debuffs continues b/c it's from her leadership. They keep gaining TM and finish you off.
She used to be a hard counter to CLS, but now CLS is a hard counter to Padme. It's brutal, I know, but true.
