My toon was a monk, a class that gets extra experience for an hour at a time. I picked at it more than I have in the past, so I benefitted more from the 150 percent "rested" experience bonus. If I wanted to run a dungeon for quests, I fired up a high-level character on a second account and dragged my little toon through them. And having leveled dozens of characters to 100 and 110, I knew every zone and every objective.
Gold-making blog Just My Two Copper suggests that enchanting will be quite the money making profession during the initial phase of Patch 5.3. This is because with players racking up new shield heirloom items and new PvP weapons and cloaks, and the tendency of PvP fans to max out every potential stat in their gear to win their matches, they will spend a pretty penny on Enchanting boosts. Just My Two Copper expects direct enchanting fees as well as the costs of Enchanting materials to rise during the start of the patch.
Stormheim is the zone you want to start it. For some reason Legion treasures are not worth any experience like they are in WoD...except in Stormheim. I haven't been able to find out any reason for this, and it's possible it may get fixed/nerfed at a later date. But for the time being you REALLY want to jump from treasure to treasure to augment your quest experience.
