This, you can drive it close but you put it at considerable risk doing so depending on the map and commanders of the opponent.
Its a artillery piece guys. it should be effective at max range as well as more effective at close range if you drive it up that close. (lol)
Right now its drive up close or don't kill anything at a max range barrage unless you have like 3 of them.
this kind of thinking is what prevents you from effectively using a unit. its like saying, oh, g43s should be good at long range cause theyre rifles! but no, they work best at medium and close range. the same applies for the panzerwerfer. sure, the katy is better at long, but the werfer is superior at close range because it drops its entire paylaod at once, and saturates the area.
anyone with half a brain WONT drive the pwerfer into range of AT guns and sorts. shoot from behind shot blockers or fog and then immediately reverse after its done firing.
also the pwerfer DOES indeed wipe or bring down to very low hp AT guns when firing from close to mid range.
while it is true that it is quite far up the tech tree, i dont even bother going t3 when i play wehr anymore. you can stall at t1 and t2 for abit, and you can actuall get a panther by around the 14-15min mark, using a luftwaffe supply drop cuts the time by about 2 minutes every time you use one. panthers are just superior to every piece of allied medium armor, and are the only thing piece of non-doc armor that can effectively tackle jacksons. usually i get a pwerfer after i feel like i have armor dominance and need a way to clear out late game infantry.
