It does have 0.75 moving accuracy but accuracy is not used when facing anti-tank guns or infantry. Also it has 7 speed which is indeed fast, but it's the same speed as units like the T-70 or the Stuart or the Cromwell.
It's a doctrinal unit, it's supposed to be good. Adjusting it further has to be done in a careful way. Nerfing its hitpoints to 400 so that it can get snared with one Faust would be a huge nerf. I would prefer baby steps and remove its oppressiveness (the fast call in and re-call in times) first before going after performance (which always has a good chance of ruining the unit).
Difference here is that it vets very fast with high AT/AI capability and its lower XP value compared to Cromwell and it gets the speed bonuses at vet 2 and not at vet 3.
The mobility at vet 2 speed 8.4/ accel 3.1/ rotation 45.6
