After playing with the new patch I think they are mostly fine, but the mortar emplacement changes are ridiculous. Once the heavy barrage is unlocked you can hit half the map with a 250MP emplacement. At minimum they should put the heavy barrage on a shared cooldown with brace to give the axis some counter play.
PPSHs are underwhelming and often a downgrade on open maps. Replacing them with SVTs would go a long way towards making some of the more underwhelming commanders viable.
I would rather lose the AT shells on the ISU entirely than deal with a range nerf to HE. It's already extremely slow and vulnerable, add in buffed panthers and nerfed SU85s to support it and you spend the whole game repairing it. What is envisioned as counterplay to the Elefants now that ISU, SU85, T34 and Zis are all nerfed?
Its high explosive range is reduced by 10, so you're already slow and vulnerable unit now has to get closer to do its job which makes it vulnerable to dives from the newly buffed Panthers which the newly nerfed SU85s are worse at fending off. Plus less armor.
Since the SU85 and ISU are getting nerfed and the T34 ram is locked with vet now, what's the most viable way to fight an Elefant or other super heavy in team games? The standard answer is flanking but with how dense 4v4s get and how squishy T34s are (plus Panthers are getting buffed) that's often not viable, especially since when I use the Elefant I mine all of the flanking routes.
