The core of the issue is whether tanks actually contributed more than just exploitation? Did they aid the advance of the infantry in a decisive way? Could the infantry just as well do their thing without tanks?

Here it _seems_ we disagree. If I understand your position correctly, you argue that the effect of tanks in an infantry supportive role is negligable.
Secondly, tanks (as in panzer divisions, as in the whole division not just the tanks of the panzer division) in panzer divs and TC, cannot by themselves establish breakthroughs and cause a lot of casualties.
My argument comes down to that a tank in an infantry support role isn't really making use of the tanks primary asset: mobility. If you use a tank as an armoured 57mm/75mm/76mm/85mm gun (to use the most common mid/late war calibres), you're wasting the mobility. You get a slow advance. Sure, the infantry probably appreciates it, but you might as well be using an assault gun for the same job, also because within no time some tanks will be brewing up because their frontal armour normally can't withstand prolonged fights.
In that case, to continue the link in the discussion to fighting in the west, you end up fighting like the Western Allies: you move the tanks in with the infantry, either the infantry or the tanks start taking losses and refuse to go further, reinforcements are called in. The result is a situation where a potentially very small enemy force, a few squads well equipped with MG's and Panzerfausts and an (self-propelled)AT gun, for example, can slow the advance down significantly, because the tanks are forced to stick to the infantry.
What the Germans understood well was that tanks were not made for that kind of thing. If the tanks encounter stiff dug-in resistance, you let them go somewhere else and let the infantry fight the enemy. You don't start banging your head against entrenched positions, a situation where tanks are just big targets.
In game terms, this means that when mobile units attack well entrenched units, they can suffer, but generally speaking when they attack some, say, Rifle division that has already been displaced by the infantry, the Soviets are going to take a beating, although losses can still be somewhat unimpressive (no argument there, I've made a couple of suggestions on the tester forum for improving casualties caused by mobile units).
If tanks attack well entrenched positions, they're probably at their most vulnerable.
Think of it like this: you have infantry and tanks at your disposal, in separate units, and you encounter an enemy position, knowing that both forces could dislodge the enemy. You could attack the position with your infantry, removing the enemy from their positions and then send your still fresh tanks after them, or you could send your tanks in to fight the enemy and then...order your infantry to walk after the enemy? The latter option isn't going to do you much good. The enemy will have plenty of time to reorganize as the infantry you send after them is easily slowed down by a couple of delaying actions.
I appreciate your efforts ComradeP, its good to hear that suggestions are made to improve the potential of tanks.
However, huhmmmm, you didn't really answer the questions

Obviously we all agree that using panzer divs to exploit a pre-made breach is surely preferable to having to make the breach with the panzers/TC.
I certainly won't dispute that tanks/SPG are most vulnerable when attacking highly entrenched positions, but then again, so is infantry, and they don't have 100cm of hardened steel to hide behind.
Tanks and SPG's are more or less the same when supporting infantry. Certainly, SPG's were probably slightly better suited but the principle remains the same, direct fire support to help the infantry overcome enemy strong points.
Regarding tanks going around strongpoints, couldn't agree more but surely this is something that considering the scale of the game must be abstracted and taken into account by the engine, not the player, as it is very tactical in nature. It is also something in which the germans excelled and the Soviets didn't get right till far in 1943, perhaps even until operation Bagration in 1944. Certainly not in 1941.
But the whole discussion resolved around the effectiveness of panzer divs/TC in the attacking role which seems underrated while at the same time Soviet rifle corps are the real killers even without tank/SPG support.
I'm also confused with the Normandy example. IF I understand correctly, your point there is that you're better of sending in the infantry without the tanks because when the infantry bogs down, your tanks stop too. Right? Doesn't that actually contradict the statement that infantry doesn't need tanks/SPG to help them overcome strong defenses?
Seriously, the question remains:
1. Do Soviet rifle corps need tanks to overcome highly fortified enemy positions or can they do equally well with lavish arty support? The current consensus is that in the game, tanks are reduntant and my understanding is that you support that design decision.
2. Are panzer divs or TC/MC capable of effecting the breach themselves if the situation calls for it? Currently, the consensus seems to be that in the game the panzer divs are too weak and cannot overcome strong defenses better or even on par with _good_ strong infantry divs. Hence, the statement that armour is underwhelming.
Question 2 is especially important when looking at the issue from the German perspective after 1941 when your infantry is simply not strong enough to make the breach for you and the German player must look at his panzer divs to that for him. As such, the position I'm defending is that yes, Panzer divs. could make the breach even better because of the prime asset it had: tanks (and obviously in a combined arms situation). Was it better not to employ them as such is beyond question. Were they employed in this role, even by the Germans, is also without question. Just look at Kursk, it were primarily the Panzer Divs, and panzer grend. divs. with the tanks in the vanguard, leading the attack, together with the infantry of those divs, that did most of the fighting simply because there was no way that ordinary infantry divisions would stand a chance to crack those entrenchements without tank/SPG support.
Nobody will dispute that infantry made up the vast majority of the armies but, honestly, whenever there was an offensive, tanks were crutial to the success or failure of said offensive IF terrain permitted the use of tanks. As someone else has remarked, mobility is not only movement after breakthrough, but also using that mobility on a tactical scale which is not under our control.
So, to come back to the original post, is the current game as is, leaning toward favoring the Soviet player? I'm still inclined to think it is. If the German panzer divs would be "upgraded" to be able to perform closer to histrical that would go a long way to even the score...IMHO.
