My group just defeated the stag lord and hit level 4. I was considering Efficient Explorer and other means of boosting the rate we hexplore. But the rest of my party doesn't seem to care. One player doesn't think we need to reconnoiter every hex. Another thinks we do, but can take as long as we want to do. The third just doesn't care. There's a feeling that all it would do is lower the number of camping rolls we make, with an undercurrent of we could just skip those rules in the first place.
Personally, I'm the type to go for a 100% run and be thorough, and I feel like time pressure must be a thing eventually, if only when Kingdom Building enters the picture. But I haven't found that to be the case yet. I'm playing a kobold chef sniper crossbowslinger, and my skill feats are at a bit of premium as the party's crafter.
Does the number of days you can take to hexplore, travel, or whatever ever actually matter? How much did your groups devote towards optimizing that experience?
