FWIW I stopped running expert this event. Out of curiosity I started running alternating standard and expert, taking note how many gold chests drop. After ten runs of each I had 8 gold for the standard, five gold for the expert. Been running standard ever since and still only three times overall (20+ runs) where I did not get a gold chest. They don't always contain the currency, but neither do the golds on expert. And the rainbow chests are too rare and have a too wide variety of items to be worth it imo, which would be the one reason to still go expert.
