Feedback is useful for something like this, mainly for future years. The general complaints here aren’t really useful since they’re currently based on nothing but hypotheticals; only the Brown (and maybe White?) lot(s) have sold out so far, as of day 6.
Odds are, scarlet and green won’t sell out at all given most people with lower priority points won’t qualify for the donation minimums. Yellow will probably sell out but may also be borderline due to the minimums, but even then it’ll be after 1+ weeks at least.
The time slots, etc. could become issues if we start winning again, but for now I’d say the best thing to do is give level headed feedback so the glitches get fixed next year and beyond.
