[2020] Hux Dominance Bugged?

I’ve prioritised (and spent a little on) getting Hux to 7* and reliced, as his abilities can make a first order team a sort of B+ squad that can counter some good teams if there’s any weakness in how they’re set up.

The leader ability reads:

*If all allies are First Order at the start of battle, General Hux gains Dominance at the start of encounter and at the start of each of his turns if he didn't already have it, which can't be dispelled or prevented. Dominance expires at the end of the turn whenever General Hux is critically hit.

Dominance: Enemies can't counterattack; First Order allies have +100% counter chance and +50% Critical Damage*

I’ve noticed that in a lot of battles, Hux loses dominance and just never regains it. He should regain it every other turn if he’s getting critically hit. But the regain just isn’t happening again, ever, quite frequently and against a variety of squads.

I’m going to start tracking more but thought I’d post in case I’ve misunderstood the kit (it’s not particularly clear...) or in case anyone else has noticed this behaviour?
