Its useful against lightning damage but I wouldn't exactly call it a hard counter, just a benefit should you get hit by lightning damage, especially in multiple amounts like chain shell or ryesers.

A combination of the two for an excel jump-starter accessory would sound pretty cool to me (Where in it builds up excel charges every round, but you lose the lightning damage interaction from gloves), and for the listed reasons above, still give use to the classic combo with 2hand instead.
