Also, the removal of sighting for Elephant and ISU-152 sucks. One might not get scouts close due to armor waiting and I thought that was the whole idea of the Elephant and ISU-152, to be able to outrange and pound such enemy at the cost of severe mobility decrease. It was totally fair as it was.
Disclaimer: All IMHO
KV-8 was brought in line with other flame attack units and vehicles so I think it should be fine.
ML-20 was over-performing compared to the leFH so it was brought in line with it. With all the artillery the Brits can bring plus existing units, infantry will have a hard enough time surviving as it is. I'm glad you can no longer build the ML-20 and leFH inside the base.
leIG and Mortars still have a slightly different role, 120mm included. It needs to be confirmed but I think Mortars will still perform better in urban areas and leIGs in the open. Mortars are more likely to squad wipe in my experience.
"In line with it"???? It's not supposed to be in line with LeFH, it's supposed to have noticeable higher damage and longer range. Not building in base is fine.
Infantry flame upgrade to burn people in buildings, ok, but the KV-8 is supposed to be anti-infantry. I'm not buying a KV-8 to get someone out of a building! And now people can get in and out of buildings in no-time as well.
