I thought we would see more of the God's Knights in action during God Valley and even see some Garling hype, but none of that happened.
Maffey was casually cut down by Whitebeard
Sommers was attacked by Ray and smashed through some buildings
Garling was defeated by Rocks
And finally Gunko and the other God's Knights weren't shown fighting anyone notable or getting any major focus other than attacking civilians
