If Hera's Leader Ability Worked With Any Allies...

There are a lot of uniques that are very powerful and just adding a single one of them to phoenix without changing anything else would have the potential to be overpowered. Stuff like Fulcrum, which would essentially make your entire team debuff immune, or JKA, anytime anyone goes below half health the rest of the team gains full TM and a damage boost... yikes. Old Ben's would be crazy if applied to everyone. Or General Kenobi just giving everyone a 65% foresight chance every time they ended a turn.

Those four all together under Hera seem like they'd be pretty much impossible to kill while still dealing out a ton of damage, and I'm sure there are some others that would fit in well too, Chirrut's health steal + counter comes to mind...
