I often see people recommending it, but I've never really understood why. The 10% boost isn’t all that significant, and it only works when you're at full health, which isn't something that happens often in the middle of a fight. To me, it seems like there are plenty of other options that can easily outperform it, especially since it feels so situational. It might be somewhat useful while exploring, but overall, I don't think it's ever really necessary.
