This change does not make Panzerschrecks worse. Their effectiveness against medium and heavy vehicles should stay roughly the same (damage per minute is balanced out with decreased damage but increased accuracy). With the enemy kiting and reacting, I expect most shots to take place around maximum range. For example:
Against a medium tank (20 TS) they currently need (640/120=) 6 hits, and at long range with a 56% chance to hit that will take roughly 10.7 shots or 5-6 volleys.
With these changes the shots to kill would go to (640/100=) 7 hits, but with 72% accuracy now, it would take roughly 9.7 shots, or 5 volleys.
There would be a small difference in synergy with other AT weapons (for example a tank that took two hits from an ATG would require 4 PS shots to finish rather than 3) but again, the higher accuracy should generally compensate this.
Obviously numbers can be tweaked further to finetune the changes. If tests would conclude they'd effectively become a bit worse at mid range then accuracy there could go up too, although the better max range performance would likely be a better trade for slightly worse mid range. But the point (goal) is that this change wouldn't really make them worse against mediums and heavies in sustained combat while 1) decreasing the alpha strike of Schreck blobs and 2) making them more reliable against light vehicles. I don't really see how this would make them any less cost efficient.
i thought one of the main positives for shreks is the alpha strike, which is why it has the longest reload. For me, the reason it sucks vs LV's is due to the long reload. But overall i think its a positive change anyway gj.
Whats your opinion on volks? honestly at 260mp i really struggle with them until i get an mg34 or LV's out. Similar to USF, i was under the impression volks need to be very cost effective like riflemen, but they are not and i really think they are the main reason why OKW is hard to play with.
