Nothing you face in 17th SS requires a pak 41/43 should have brought more light AT like the Panzerbüchse because there is such a light vehicle/half track meta right now
Pharaoh just use a wide combination of Support units to overwhelm you, it doesnt matter if he needs the Pak 88 or not, the Pak 88 will always be a very dangerous presence on the field, wheter its HE, or AP and will attract enemy response. If there is an overwhelming amountof support weapons on the map, the enemy wont know what to target first. Its a very good strategy but of course, it doesnt always work, for you need your units to survive in order to build.
