I did get what you were saying, I just acknowledge that what you want is impossible in the game while trying to sugarcoat it by pointing out that the things you CAN control (gear and unlocks) play a greater role in your experience of content than the things you can't (xp)

Also, if you really want to experience it that way, I'd advise looking into when the content came out in the first place and do it in that order as well. Though, doing raids will be difficult if done using gear that was actually available at the time. Maybe if you can find 7 other people with similar interests.
