Not really, just play the PzIV strength: Very accurate sniper.
In a PzIV, with periscope, 100% crew with 2 minor qalifications I have often tracked much bigger tanks and chewed my way through them..untill they go boom.
I love tracking from afar in the PzIV...the long 75mm is a sweet gun and it can pen a KV3 from the fron, just aim a bit to the rigt of the drivers...weakspot, surprise many KV-3 tankers when they get penned there
Again..player skills determines how they play their tanks....and to think the PzIV is a slugger/brawler is doing it wrong
