How would you rework the Assault class?

As of right now, Assault class has (IMO) the worst signature gadget (injector) in the game. It's too slow to use & the effects are too short to be that useful. I've seen opinions claiming that it should be replaced by the ladder or the beacon.

I read online somewhere that it was supposed to be a full heal like in 2042, but they changed it for balance?

I'd also suggest that perks for the frontliner subclass need a small rework. For example, I don't think reduced fall damage or the beacon injector effect is that useful compared to perks from other classes.

Thoughts or opinions on how you would rework this class?
