Can I skip the main campaign in Diablo IV and go straight to the other content?

Can someone boost me, or is there any method or service that allows me to do that?

If I skip the campaign, do I miss out on any content? For example, something like Kanai’s Cube?

Can not skip campaign until it’s been finished at least once.

You can be boosted.

No you won’t miss out on d3 items.

So i can enjoy all contens and end Game whitout end campaign?

No.
