Stack Sizes
This wasn’t the case in GW1 so I doubt that this is going to change. Once I get a full stack of materials, I move it to a bank storage tab so that I can still drop new items with the “deposit collectibles” feature as I am eventually planning on maxing all 8 crafting disciplines. However, once I get past an item level on all professions, I’ll probably start selling my extra stacks on the TP or donating them to my guild bank.
