Same here. They rained like candy in the Apollyon event but back then I had champion status throughout the whole event period. My guess is this is to encourage people to shell out for Champion status so their loot drop chances are increased. Weaponized RNG designed to target the ol' steel reserves.
I DO have champion status. Still got 1 piece for the Warden in 13 games (as an example).
Jeebus! That's pretty much my experience as well except I don't have champion status. They went a touch heavy in the weapons grade RNG this time around.
