What's weird is that you ask a loaded question like Ostheer not having a "stock unit" for the TD role (a role you don't define, considering current units), but then immediately make the other assumption that they are without TDs entirely in the next sentence.
Hey calm down. I´m just asking why Ostheer do not have a single TD as a stock unit. Am I saying or asking something wrong? They do have Stugs, yes, but they are not purely Tank Destroyers. Ingame they were converted into one.
Showing a picture of unknown origins (and clearly ripped from a publication) hardly helps, I don't know why people do it. Are you suggesting those are the only tank destroyers that Relic can choose from?
Of course that I copy-pasted that image from another publication. I am not a designer, nor a tank engineer.
Thats the wierd part. They have more than 10 TD at their disposal, and included 0. Same thing with light tanks for Ost.
Anyways the answer is game design.
Naw OP is basically saying "I want these units to be stock in the game for Ostheer", and of course ignoring the three facts that Ostheer has good anti-tank, OKW has some units in the picture, and what's considered weird is often not someone else is doing something wrong.
We are not talking about AT-guns or OKW.
