Back when we had the Elemental Well system, there was a mod called Well of Ions, which increased your melee damage for a short time when you picked up an Arc elemental orb. They should bring that back, and merge it with Amplified. It would give Amplified a more offensive function, and synergize better with the Arc subclasses' close range abilities.

Other than niche stuff like Eddy Current or some prismatic fragments, there really is no direct benefit to amplification other than the speed/jump boost (that I can think of) so that would be a nice change
