If sarcasm is included as an insult here then i apologise.

Again, if it takes that long to build peerage and etc then we might not see about Issei's progress as a High Class Devil, we might only see some statements how Issei has become a succesful High Class Devil or just some stupid time skip. It's still unclear whether or not Ishibumi wants to make any story about Issei after he graduates from his high school.
