Question, why does Bard and Machinist share the same core mechanic?

[Ashkendor]

Melee hit twice as hard and can move around all they want. Granted, some of their skills rely on positional attacks, but it's still kind of a double standard especially when the bard/mch spends most of their levels with full mobility and only gets cast bars in their twilight days.

Melee are restricted to melee range. Casters and healers need only stay at range to stay out of their way.

Having a random derp-bard running around and dropping mechanics on you was annoying as hell.
