This would just bring a truck load of new balance problems for very little potential gain in the quality of game-play.

The commander is fine.

Radio intercept is nothing new and neither is the concept of legal map hacking. Radio intercept, spy network and interrogation training all provide intel on enemy activity.

PPSH guns are good, but the doctrine lacks other elite infantry. There will be no dedicated AI assault infantry on the field other than T1 units, and there will be no infantry based AT-support other than field guns. As a kind reminder to the germans, grenadiers have a stock weapon upgrade which is more powerful than the ppsh upgrade. They also always have access to panzergrenadiers which can perform as both AI assault infantry and infantry based AT support.

Conscript repair is also nothing new and is not something that was ever considered OP. It's a nice ability which gives you a decent bonus but is nothing special. Just like hit the dirt, panzer tactician, spotting scopes, etc.

The T34/85 is a P4 painted green. Whoop-te-do. If you can't deal with this unit with all the powerful german AT-options then you might have to look at your strategy.

The single IL-2 strafe is 'OK' at best. 2 mines will likely do more damage for a cheaper price. Out of all the soviet off-maps this one ranks very low.

Mechanised assault groups work very well as an alternative to flamer halftracks. Mech assault groups provide mobile, stable DPS that can easily cut down conscripts and force shock troopers off the field. As a bonus, it doesn't cost you any munitions so you can buff up your grenadiers with LMG42s and/or save up for some Panzerschreks.

"Both of these look like an Ost clown car, but both come too late to act as one. By the time 3CP comes there are plenty of things that can kill them[...]."

This is plain false. At best there will be a single AT gun on the field. But if you are spending munitions on LMG42s, your opponent will likely not get one that early because he knows you can't afford a flamer halftrack and mech assault groups are a rare sight.

Unlike the soviet clowncar, the 250 is also very resilient to small arms fire and won't die to a single AT nade. If you keep your pioneers close, you can quickly repair the 250 after an AT nade to continue the onslaught.

It seems you just need to aim your grenades better if you are getting such low kill counts.

Protip: Aiming at maxim gunners is not always the most optimal way to use rifle grenades. There are 5 other crew members that can't swiftly dodge the grenade. Some of them are bound to bunch up at some cover. Aim it at them instead and you will score a lot more kills.

The only change I would like to see with blitzkrieg is a reduction of its duration.
