Having recently picked up Descent while I await more Imperial Assault app support, I’ll say that we could pretty easily incorporate the Delve mode into Imperial Assault as either a raid on an Imperial base that is randomly generated each time, or else a trial where you are fighting in an arena against different enemies similar to the existing raid mode and perhaps mimicking the arena fights in Jedi Fallen Order.
This would tide us over until you wake up and give us Endor, Mandalorian, Rogue One, and Clone Wars big boxes.
sigh one can dream...
