But that can't be done either, as the Dark Troopers weren't vehicles.

Phase 3 variants were able to be worn as a battle suit.

Battlefront did Dark Troopers just fine until they made their blasters more accurate and increased the recharge rate of their jump packs.  While those changes made them more hardcore as Dark Troopers would be in actuality, it only made winning in the Galactic Civil War as a Rebel as hard as it already was to be a droid in the Clone Wars.  Whether it was tards whining or developers that were tards, the only patch ever released for that game only made it worse.

I think they'd be an acceptable class, either an additional class entirely or a replacement following a merger of either Trooper and Support or Trooper and Heavy Weapons.  Or perhaps Heavy Weapons and Support.  Just need to make sure no one goes overboard with them.

Take a lesson from the Battlefront series:  they weren't broken, but they tried to fix them.  Luckily, their tweak on the Jet Troopers didn't have an effect, positive or negative.  But, unfortunately, they didn't learn the lesson that it's important to remember the nature of whatever it is you're trying to create...  unless they wanted to make something in the semblance of crap.  I'd believe it.
