If Germany builds in Navy significantly they can take Norway off the table. unless allies are staged in sz 109. If allies staged in sz 109 Italy is not threatened. Norway is great location to even throw transports at IF Germany doesn’t have a fleet to dominate it. I personally play with a large German fleet that takes sz109 off the table. If Allies want to waste money attacking Norway they’ll either have to sacrifice those transports and replace every turn or leave the protection of their air bases with their fleet and lose their invasion assets entirely.
Losing Norway for some time is worth it if Axis destroy the possibility of allied invasion of mainland Europe. It’ll be 4 or so turns before they can threaten again, by that time Germany has dealt with the incursion in Scandinavia and Italy is rampaging through North Africa and Middle East. The cost of taking the heat off Italy can be detrimental.
Piecemeal dismantling Germany only works if allies have guaranteed naval superiority and the freedom to choose their battle ground.
Don’t get me wrong, I like invading Norway. I have just found that overwhelming German naval presence completely shuts that down as a viable option. Insomuch as a move to threaten Norway requires heavy commitment and telegraphs the Allies intent. Preparations can be made to thwart that effort, Italy remains unthreatened and can bolster it’s position in the Mediterranean.
I like keeping the pressure on from sz91. It keeps the Italians in check, they can’t operate freely with their limited assets if they want to protect Rome. If Germany doesn’t protect the seas Norway is a great place to hit. Most players do not invest in a large German navy so it’s a great way to whittle away at the Axis position.
I don’t play that way with Germany. I found instead of wasting all those IPCs trying to protect multiple fronts I started dumping them into German navy. That covers the North for me. It’s had amazing results for Germany. Try it out and you’re gonna be really scratching your head trying to figure out a way around it.
