You seem to be under some weird Impression that other artz pieces are somehow accurate on long range.
Let me burst that bubble of delusions and inform you that all other arty pieces are equally shit at max range and all mobile arty that can, ALWAYS SHOULD come as close as possible before unloading barrage, Katy being prime example here, where it wont even hit targetted sector if used from max range.
stop putting words in my mouth. Compare katy vs PW at close, mid and long range and tell me which one is best at all ranges. Have u never fired katy at close range and obliterated sqauds in 1 salvo? go play the god damn game instead spending ur life on these forums
