Why would I even build an Elefant any longer? That unit is designed to be caught with its pants down. Now with incredibly thin side armor.
1) There is no side armor in coh2 and never was.
2) Doing less reverse raids towards allied AT might help a bit, eventually learning what covering with ATGs is.
All heavies had no weakness.
This is why everyone always went for them, limit or not.
There were houndreds of games lost, because despite perfectly executed flanks with multiple vehicles, heavies weren't going down due to sheer armor they had on rear.
You might want to consider medium armor more now.
Heavies still are powerful option, just no longer the only option.
