I don't think it's that big of a deal anymore in year 2. The only time elemental damage was important to me was during y1 nightfalls that had elemental burns that would deal a ton more damage. Now a sword can pretty much one shot anything. I haven't ran into an enemy yet where I even bothered pulling out the proper void, solar or arc weapon to take a shield down. Throw an arc frisbee from the exotic sword and down they usually go.
