I repeat my question. Do the Germans really need a killer tank that do all of that? So what if the jadgpanther could ONLY kill a shermen from 2,000 meters. Again a tank / tank destroyer that can one shot kill the enemy 90 / 95% of the time is more than enough. The Germans desperate desire to gold plate everything and make super solution was a big part of their problem in general. Having twice or more of Panthers which burned less gas, were hugely less of a logistical pain to operation, etc sounds like a bargain to me.

I don't disagree with you that the idea of heavier independent tanks vis a vis main battle tanks was inferior; but keep in mind the concept of main battle tanks wasn't really established till the 50's and in the west not really accomplished till the 60's and later
However, EVERYONE, the French, the Americans, the Russians and the British all thought the concept of making robust heavy vehicles for independent operation was a good idea; so the vehicles have to be looked at in context
The panther in german doctrine was a medium tank
The tiger in german doctrine was a heavy tank
The argument that heavy tanks should have been abandoned in favor of more mediums hits all the major powers as having made that mistake; but in the context of everyone having and wanting heavy tanks, the tiger could hardly be considered wasteful, given that it was generally superior to it's competitors in class
