The issue is most classes don’t benefit from the inspiration crescendo because there super isn’t compatible with it. (hopefully they change that in the rebalance)
only musky, bard and ranger can benefit but musky generally isn’t being played if there’s a bard and when it does the musky super is used for the instant refill rather than the increased respawn speed of orbs.
So only bard/ranger really benefit from an increased super. It’s great for rangers.
For bard from my experience the bar when you super gets refilled slightly like it should during your super but I never tested if that actually increases the length and/or other players damage boost length. It should increase everyone that’s within range for an extended period of time.
