So, Azeroth got shattered earlier this week.
Before the order of zones by level used to be something like:
Kalimdor: Starting zone, The Barrens, Ashenvale, Thousand Needles
Eastern Kingdoms: Starting zone, Silverpine, Hillsbrad, Alterac / Arathi / Stranglethorn
However, these zones, at least in Kalimdor, no longer connect this way.
What is the expected progression through the zones now?
Note: I'm actually curious all the way up to 60, but I understand the tree gets a lot more complicated if you go that far, as the number of zones of those levels increase.
