Wait 6 or more months till nerf.
Answer from a couple of months
What we could try is giving it lower penetration (around 90) and adding deflection damage of something like 50%. That way it will still be lethal to snared/rammed mediums and Panthers (guaranteed rear armor pens and even with deflection damage when hitting the front armor the rockets should do enough damage to kill a 50-75% hp medium tank) while reducing the effectiveness against heavies by around 33-50% as most have around 150 rear armor. Essentially the same was done for AT Overwatch.
But the commander will already take quite a hit with the increased SVT cost, so it's probably better to wait and see if it'll still be needed to go after the AT strafe too.
