One of the biggest things we are considering for v48 changes is to reduce the number of main Campaign stages from 5 to 4 in order to address feedback about length of Campaign and saturation of Artifacts; such a change would include bringing stage 5 difficulty forwards rather than cutting it off as we’re looking to make it shorter with less long path Artifact accumulation, not greatly alter difficulty. We are seeking community feedback on whether such a change would be viewed positively or whether you fear that would undercut the challenge or perceived accomplishment of 5 stages. — Update notes
