That's silly. There is no way you will always have enough units in front of a JT to kill a ramming T34. AT-guns will do nothing because unless you have 4 of them they cant kill the T34 fast enough. It's also not realistic to have every single inch of the map covered up with mines.
I understand a lot of legit arguments against OKW units being too good (like old Command Panther for example) but trying to somehow make JT look like it's too good or easy to use is just stupid. JTs were never used in 1v1 and 2v2 and only very rarely in 3v3 and 4v4. There is a reason for that.
The changes made the JT easier to use so there is a chance it will be used more often now but at the same time I also feel the balance approach was very lazy and made the game more boring because it reduced the few existing differences between JT and Ele even more.
all you need is literally 1 volks squad if the tank is coming from the front, or 2 if coming from a flank (Assuming you didnt do anything to protect the flank of your nearly 300 fuel case mate unit) the jt takes sligtly less than half a normal tanks heath off leaving it WELL beneath the threshold for a snare. snared tanks dont ram and snared tanks that were diving to get a 70 range unit bhind your lines are dead tanks, assuming you have done literally anything at all aside from call in the JT and expect that to win for you.
if the enemy gets their tanks or infantry that far behind your lines you are supposed to get punished for it, im sorry getting punished for fucking up feels like a balance team attack against you...
i know they do a shit job of showing it sometimes, but this gme is supposed to be about combined arms. support your units and they will do much better
