If you had the option, would you burn 200 BCX of penny cards in exchange for one Rift Watchers pack?
Heck yeah I would. Penny cards are roughly 2$ for 200 BCX (If not less) and RW Packs are over 2.9$. So it would make all the sense to go for it, until RW packs get dumped under 2$.
While it would be good for burning a lot of cards, it would be straight violation towards RW pack investors in my honest opinion.
EIther way, I'm voting YES for this proposal, as I don't have much invested into RW myself and I would love to inherit some of those cards from that edition :)
