I really can't see the point of the Sturmtiger unless you intend to use it as it was designed. It's supposed to be an extreme risk-reward unit, and if it can one-shot a medium tank or wipe a few squads then fine. It has a long aim time and is vulnerable during reloading, and it doesn't fire automatically like most units. I think its flaws were always obvious.
I think it's a huge shame it was made doctrinal as it was never designed to be, but nerfing it seems like a mistake. If it's just going to end up as an AVRE or Stupa clone then I think it's essentially a waste of a unit slot.
