Im glad the healing is addressed, comparing it to okw healing(which thankfully is also getting addressed) when going puma the ukf healing options just knocks it out of the park. In your hypothetical scenario you would probably avoid the sturms just as you do in every other allied-okw matchup until you have sections/uc which are super powerful t0 units compared to kubel and volks
Except okw will now have reliable option to backtech for medics if needed. There is also the fact tommies are much more expensive to reinforce than volks, meaning the fact their healing is getting delayed this much is very painful considering they have a really hard time pushing into entrenched position. Luchs is also getting omega buffed vs garrisons and green cover so you can see the choice of going mech of battlegroup as an actual decision to make in the early game. Volks don't need healing as much as tommies do in the early game.
