Super fast. It was over before it even started. But I did snag some packs. @methodofmad/whoa-that-was-fast-riftwatchers-bonus-packs-sold-out-in-a-few-minutes
We will see if it was worth it. I noticed Chaos packs dropped below $1.80 this week on Tribaldex. That's a pretty long slide from $4 and a voucher when purchased new.
