The German view from the tanks was degraded, especially the Pz.4, which had a very reduced view because of the side skirts.
Whats the source? Commando-hatch was above skirts, so distance-view wasn't locked.
Way more important was fighting room design, the reason why german vehicles had no angled armor (first). Reload, communication and working-space was key of german vehicles. Not saying german armor was good, but the battle effect was superior, even Pnz.III was able to counter early T34 with ease by simply punshing untill armor cracked. And with Pnz.IV-F2 they had a very effective answer. -> WarThunder doesn't reprecent T34 good. ^^
But all over, ingame T34 armor is wrong repecented, should be better. But diffictult to make it not OP.
