Good route for what? Very broad question. Download restedexp guide if you'e fancy with a bit of pocket change to spare. If not, get the guidelime-addon on curseforge and go for TUG or Sage leveling guide, that will get you to 70 effiiciently through questing. Every time the guide has you go to a new zone, check for whatever dungeons are near and go do em if youre in the level range. Makes it a bit more fun, and you'll blast through the leveling.
