The material caps NEED to be increased, and honestly totally removed. There's no worse feeling than having a full vault and character inventory because it's full of garbage exotics I masterworked to not waste materials (which are still partially a waste) and having my ascendant shards and prisms go to the void because there's only a cap of 10 and 50, respectively. This is nothing but a constant slap in the face every time I play a GM and makes me not want to farm them whatsoever knowing that most of my end-game loot is going to vanish into thin air.
