stop looking at the unit in a vacuum, and look at it in the perspective of the WHOLE faction. the crocodile + at gun synergy is extremely strong. with basically pak40 stats, it has good chance to penetrate even heavy armor at max range.
True; consider other things together. The 6-pounder just got a price increase (deserved IMO considering stats comparison with Pak40), but the Pak40 performs better in general not because it has better stats, but because it will more often penetrate Allied tanks with less armour and so get vet faster on top of TWP. With the 6-pounder's 190 pen at max range it will still only have 59% chance of penetrating Panther frontal armour.
On top generally Axis has good weapon-team wiping arty in the form of Pwerfer (even when I move as soon as I hear the sound I almost always get decrew) and the stuka. This leaves Comets and FFs as the main AT.
In addition to the price increase the Croc's stas also got nerfed. While I saw the Croc probably needed some nerfs as it was really difficult to take out while supported, I cannot say whether the exact changes are the right moves since I haven't played that many balance preview games. I can say, as a player, if the Croc remains at 230FU, I will go for comets instead since I cannot guarantee enough AT support in the form of other tanks; there is no StuG equivalent for UKF. If somehow the AT guns are taken out, or if the Croc gets engine snared and Panthers, StuGs, JP4s, etc. chase it, you're literally defenseless especially since UKF does not have snares in general. This is considering other things together.
