I know that you're able to earn one facet for free each week after levelling up a level 30 character with well rested, and the facets cap at a stack of three. My question is whether or not you're ONLY allowed a max of three per stack, or if you can start another stack to hold more. For example, I level up once a week for six weeks, will I have 6 facets (two seperate stacks of 3) ? Or will I only ever be allowed a max of three ?
