The intresting thing from my point of view is that for some reason lots of people, in this case including the developers at Relic, automatically assume German equipment allways is superiour to Allied or Soviet equipment.
The Bazooka is a prime example. Its actually a better weapon than the Panzerschreck. Its lighter, easier to handle and can effectively take out any German tank. Mediums and medium tank based AFV head on and even the heavierst from the sides and rear.
For some reason in CoH2 it even struggles to be effective at flank shots. Against the heavier tanks is completly useless.
The Bazooka also is a better multi purpose weapon with different ammo types available.
This might be intresting for rebalancing.
IMHO the Bazooka should at least have a decent chace to penerate medium armor (P4) head on. Flank and rear shots should have a better than decent chance against any German vehicle. Panthers, Tiger and Co being more or less immune to them over the frontal arc is ok. But shots at the rear armor should really be effective. Penetrating with allomst every hit and with a high crit chance.
Giving the Bazooka the ability to lauch WP rockets could also be intresting. How it should work in game needs testing. Could be a smoke 'nade, a fire 'nade or a mixture like the Obers ability.
All rocket based AT should be inacurate at long range. Hit chance against a typical medium tank 75/50/25 % or so. Maybe better at short and even worse at long range. This would make AT infantry a last line of defense and not walking PAKs. Would underline both roles that of the AT guns and that of AT inf. At short range in tight terrain the latter will be deadly in open terrain the will be much less effective.
The PTRS should get a range advantage and be more accurate. After all its a rifle and not a rocket. This could outweight its low damage. Turing them into a long range AT harrasment weapon.
Another option would be the ability to fire tungsten core API ammo. Wich would work about the same as it does with the MG42. Increase damage and penetration for a short period of time. Not enough to kill a P4 with one activation on one squad but enough to drive it off.
The only real advantage the Panzerschreck has over weapons like the Bazooka or the PTRS is its penetration. Wich is simply based on warhead size. The laucher itself is a very clumsy and heavy weapon. The laucher its allmost double the weight of the Bazooka. So how about the Panzerschreck slowing the equiped Squad down?
The Schreck is also infamous for its huge firing signature. Wich is true for all rocket based weapons but with the Schreck its worse than with most others. How about the unit wich fired a Schreck getting some sort of debuff for a short time after firing? Received accuracy for example. They simply attract a lot of attention. Could even be an option for Panzerfaust and Bazooka using squads too. This again would underline their role as short range tank hunters and not long range general purpose weapons. Maybe combine it with a "rockets target vehicle only" button.
I also find it strange that HEAT warheads loose penetration at range. This is not the case in reality. Hasn't been in WW2 and isn't now. If its about balance why not handle it by accuracy. This is the major shortcoming of these weapons. Neither the Panzerschreck nor the Bazooka will reliably hit a standing tank behond 100 m. Even though the rocket will fly much further. A skilled user usually would try to get withing 50-75 m and go for a flank shot. Even with the Panzerschreck.
Both the Bazooka and the Panzerschreck a specialist weapons. Veterancy really should make a difference with them. Maybe even the penetration could get better with veterancy because the user tries to hit where it really hurts. In this case changing the penetration profile to one dependent on range since the weapon isn't accurate enough to do so behond medium range.
There are lots of possible options without abandoning the historical roots of the game completly. They just have to be used IMHO.
Panzerschreck were an improvement/copy of the bazooka with bigger caliber and better combat success, american leaders recognized the schreks superiority and in late war designed the super bazooka with higher caliber. As far as I know the superbazooka were never used in the ww2 but the normal bazooka with improved warhead were. True that the panzerschrek was clumsy and produced a lot of smoke, but still a much more succesful weaponsystem for other things than self-defence versus tanks.
