SUGGESTION: Regarding Rocket's Scrapyard
The idea of this cute little zero energy map where we get to collect stuff in exchange for our scrap was nice to start with - seeing as a bunch of people were going to go for big ticket items - 4* crystal, Tier 4 Basic, Mastery cores - which are a large chunk of scrap, which means not many passes would be made. On the other hand, going for things like Tier 2 Catalyst Crystals is largely repetitive and quite tedious.
Maybe next time there's an event quest with this type of reward system, we could turn it into a store instead? I.E. with my 200k Scrap I can walk away with 5 Carb cores, and a Greater Ascendant Crystal in one shot (assuming my math is right) instead of running the quest 6 times.
