One concern people have raised over a character that explores very fast (like Lancer Alain) is that this leads to 'trivializing the blessing deck'.
Now, in my current S&S playthrough, I have a party that has achieved a very high rate of exploration (through a heavy-healing WotR Kyra using piles of cure/holy feast to put tons of allies back into people's hands). As a result, I haven't had to worry at all about losing scenarios due to lack of time. This hasn't made the blessing deck irrelevant, though, because Skull & Shackles has the ship mechanic to turn extra blessing turns into valuable resources, either as additional dice, or (what I've been going with most recently) additional shots at more/better loot (specifically, using the Come What May to get rid of basic/elite plunder while digging for the good stuff, but in earlier ADs I used the Merchantman to fish for whatever card type had the most important upgrades). I'm still encouraged to burn through location decks as quickly as possible, because having turns left over is rewarded.
In other sets, the same situation occurs whenever there is a location that can be farmed, like the armory in WotR, where you can leave it empty, and then spend turns looking at new cards to potentially acquire with its closing method, until you find something suitable (or run too low on turns).
So, 'blessing deck is trivialized' can be avoided as a problem for fun whenever there is something that uses the blessing deck as a resource. Should we hope for new characters/boons that have 'discard the top/top x card(s) from the blessing deck to ____', so that parties that can explore too fast still have a reason to care about the blessing deck?
