That doesn’t deny or dismiss what I have just said. They show you a shortcut and suggest the most to the point build with efficiency and least loot hunt requirement. That is the purpose of guides at the end of the day; they are nothing more than a blue print but not everyone has to obey it to a single letter. However, you can always take initiative and modify it to your needs. When you can identify the aspects of need and weak points of your build, you won’t have problem changing things around and still be effective. Take a look at leaderboards. Most of the top players have very slight diversions away from guides written online; be it passives, skill modifiers or items.
