@hollow barn Here's what I can say for now:
First off, I can't confirm yet for sure whether there will or won't be limited use codes - just that they'll have a limited time window just like last year.
But now that our promo code system is much more robust, the idea that a limited-use promo code would be any more luck-based than a limited-time code is just not true (especially for the ones on the livestream that typically last for such little time that a limited use code would outlast it).
-# As we mentioned last year, the system before did have a bug that caused fewer people to redeem it than anticipated. And the main "luck"/stress issue with the Golden Fireburst was not knowing when the videos would drop, which is something we have control over during the livestream.
Both types of rewards are special for their own reasons, and while it may feel pointless to do one versus the other, the end effect is actually pretty different, which is why we do them at all.
So in the long run, even if I can't say for sure what kinds of rewards we'll be dropping, I don't anticipate us ending the idea of "limited use" rewards altogether - just being more cognizant of when and why we use them. And I do think certain rewards don't really make sense as anything BUT limited use.
