While the drop rate of Ascendant Shards feels plentiful on Ultimate difficulty, there is room for improvement. The material economy would be healthier if at least one of the following was implemented: 1: Change Xur’s material purchases to unlimited so we can readily convert strange coins to enhancement cores 2: Add direct conversions to lower denominations of materials to Rahool (the weekly limit for changing prisms to cores is too small). For example, allow us to spend ascendant shards to buy enhancement prisms, and allow us to spend prisms to buy enhancement cores. 3: Increase the drop rate of enhancement cores in higher difficulty content. 4: Add a system that can curate material rewards based on inventory limits (instead of dropping an ascendant shard while a player is at the maximum amount, automatically replace any ascendant shard drops to enhancement prisms, or if those are full too, enhancement cores instead (should not be 1:1, instead of an ascendant shard a player would get 10 cores or whatever would be balanced. While higher rarity materials have gotten easier to obtain by being plentiful in higher difficulty portal activities, the drop rate of enhancement cores has not matched the current demand to upgrade higher tier gear. I believe the system could use room for improvement and these suggestions would vastly improve the economy.
