Leveling in the Scaling Era

The following is still in the hypothesis stage.

Sometime in the last 6 months scaling (which had been in Legion since it's introduction) was applied to all regions. When you hover over a region on a continent map, you now see (x- y) after the region name. You cannot do quests in the region until you are Lx. Most mobs scale with you until you are Ly. In other words mobs have a level between z-1 and z+1 (where z is your level) except for the Elites. So combat doesn't get easier as you level up. It takes about 20 seconds per battle for a cloth armor toon. Sometimes you can survive combat with 2 mobs: 3 or more, forget it. I haven't quested with a better armored toon yet.

The standard quests yield the same XP in all regions when your level is in the limits: about 3% per quest. Exceptions for hard quests. No more 10-15% XP when you start out in a region at Lx. There seems to be no reason to go quest in a region with a higher x if your level is less than the y for the region you are in. After you reach L(y+1), the XP per quest drops off.
