So, I've been rolling through GW with Wiggs, Lando, Leia, and Scarif Pathfinder. And it's always fun seeing him just keep popping back up.
Anyways, in all the time I've used him, his special's Offence Down is always applied. While enemy team. No resists. Never fails.
Also, had him pop up once with HP and turn meter as if I had no rebels on the field, then when he went down again, luckilly with Crit up from Leia, he popped up with the appropriate HP and TM.
