The assymetric design can be good or bad and I think most people agree that in this case it is the bad one. The symmetric design is always bad. It greatly limits number of viable strategies, is boring and repetitive. That is why if you want to search for new design of okw AT, you need to think of some new ideas, instead of copying ostheer.
Disproves everything you said.
OkW needs a normal atg that can counter tanks. Allies and axis fanboys alike hate the rak, and no one has issue's with Zis, 6 pounder, pak40 and the m1 57 being alike.
