Profile of Mr. Someguy

I think think the increased sight is actually a good idea because it actually fits the American Tank Destroyer theme. US Tank Destroyers had open tops because it allowed all 3 members of the turret crew to search for targets in all directions, rather than just the commander. Closed top vehicles, like most tanks, allowed only the commander to have a wide range of sight, via tiny vision slits around the copula. Other crew members were restricted to the gun sights for the gunner and vision ports for the loader although these didn't exist on all tanks and thus the loader was completely blind to the world outside.

Yet every variant of the Panther has options to increase its sight range; Vetted Panther, Commander Panther (Elite Armoured), Command Panther(Special Operations), Scoped Panther (German Mechanized, Jaeger Armor). And on M10 level is the Puma, who's eagle-eyed crew commander also gets the advantage of sight vs the apparently near-sighted turret crew. Imo it's just yet another real-life advantage that US are lacking in-game that makes fighting uphill against heavy armour even more difficult. Particularly ironic that Panthers do get that advantage in multiple forms.

After Tiger Ace case or Close the pocket I hardly belive in this test balance servers

There's nothing wrong with Close The Pocket. It's only viable on a small number of maps, and can be seen from miles away. If you fail to prepare or secure you're territories, that's all on you.

Not to be nitpicky, but no Panzer IV? That and the StuG IV didn't exist during the North African Campaign.

Because it has two planes that have circular vision while pretty much every other attack plane in the game has one plane with conical vision. Will probably switch them over to a cone to match other factions next patch.

Will this affect their attack behavior?

How are you defining performance?

Armour, Gun, Mobility, and Kill Ratio I'd assume.
