I think wisps are a popular contender for a mechanic that needs some work. Personally I am happy with how they have seemingly adjusted drop rates and how often they spawn but wisp pathing is still a huge sticking point. What changes would you like to see, if any?
Personally, I think the wisps attaching to the player and circling them until you get close to a rare mob would be a good solution. Player agency in how you interact with mechanics is always great and I find it frustrating how I cannot choose to “juice” one of the rarer wisps I find as it either immediately goes into a mob or paths in a way that it doesn’t interact with any trash. This would allow you to stack multiple wisps on your character at once, juice desired rares or bosses at will, and just look kinda cool. Thoughts?
