Nothing to see here!

how would you like the ATPT in addition to the tanks?

(he has this look on his face as if he knew more)

A squad of 6 ATPT's would look amazing running across desert or wasteland- closing the distance.

I'd like them to be easier to kill than a Me speeder too- 1 or 2 rocket hits. That way, they could replace the ATST at mosespa with 2 or 3 apiece and covering the ground between the landing site and the city would be more fun for both sides.
(I'd like to be gunning at them as much as i would like to be driving one into a rain of fire)

I'd also hope the ATST's get to run at some point, though not quite as swiftly, or gracefully.

I think you have a bit of a skewed view of what this vehicle is and its size or something, but it would certainly have nowhere near the same firepower as a Rebel T1-B tank.

This is more like a very light anti-infantry vehicle, practically an extended suit of exo armor for a lone Stormtrooper. If we were to ever introduce this vehicle, it wouldn't have anywhere near the kind of weapons loadout you're suggesting here.

The Firehawke is more than a match for the T1-B, the balance is just a little out of whack at the moment, but will soon be rectified.
