Class-based Keybindings

I think the game would benefit from class-based Keybindings - or at the very least options for melee vs ranged based classes.

Bulwark comes to mind, followed closely behind by Assault.  Both of these are primarily melee-based classes that spend significantly more time in melee attacks than ranged firing.

For example, my ranged classes, I like right click as aim/heavy, left click to fire.  But for Bulwark, I want to right click for block and left click for melee.

As it currently stands, I either avoid playing Bulwark at all costs, or if I change my keybindings to melee-based, I only play as Bulwark (and sometimes as Assault).

Feedback/criticism is welcome - thank you!
