Actually, on the superhero front, Green Arrow, Hawkeye, and other "super-archers" are also good candidates for imbuements. Certainly, in-universe, they're using special trick arrows for most of their stuff, but narratively, they always seem to have just the right arrow for the job. That could be modelled pretty well by giving them various imbuements (Binding Shot for net arrows, Crushing Strike or Fatiguing Strike for the infamous boxing glove arrow, and so on), and just saying that most of them can't be combined with each other.
