WoW just fucked everything for me. It was never worth the time to learn about an area, because you’re already past most of its content and getting to the next one by the time you sneezed from the book dust.

WoW has been getting worse and worse at this in the later levels after the scaling rework, BUT if you start a new character, then anything that's not the most current expansion, you can start doing the content from a lower level and actually take your time through... Well probably one expansion's story lol

So if you go to Northrend or Pandaria or whereever at level 10, you have plenty of time because you can keep doing these zones till you're level 60 or 70 or something and only then do you actually HAVE to move to the newest region to keep leveling up.

Eastern Kingdoms and Kalimdor of course are so big that you're going to have to do multiple characters to get all the storylines done without doing some at max lvl.
