That's the current way... Again... you have to open more crap you don't want. I would like the ability to reset the set of 18 when I want to. Like the re-spin button from the pirate event.
Plus the rewards are kinda lame. In the recent events, regardless of age, you had the opportunity to get 5/10/20 FPs, or, at least 2,3.5. You could get One up or reno kits without, on average, 12 attempts (clearing half the board). This event has a preponderance of watchfires and watchfire upgrade kits that (personal discussion on multiple worlds, no-one wants anyway. These , along with ritual flames just accumulate in inventory or are destroyed). Once, first day, SoK. Once, RHo. and we're 20+/31 days in. (I'm not going to get into how lame the new fractional SoKs, and, even worse, WW shrink kits are for the same effort / cost)
