I normally use one class, Titan. I am one rabbit off from the Lunar Gloom shader, the one you get from collecting the rabbits on the moon. I read on Reddit and saw on YouTube that the rice cakes drop one time per week, per class/character. So, I made a Warlock, played through the Moon story campaign (Eris has given me the Sai Mota quest), but so far a cake hasn't dropped on my Warlock. I've done countless patrols, a couple runs in the Altar of Sorrows, picked up several chests and helium filaments, and done every daily bounty for the past three days from Eris... but so far, nothing. Have the drop rates changed for the cakes? I could wait til reset, but I am a fan of the shader, and kinda wanna get it out of the way... you know, less stuff to worry about on reset day.
