With the leveling squish, we all have a general idea of how its going to work through the Shadowlands.
I know this is still at least 2 years out, but how would you like blizzard to handle the leveling experience after shadowlands?
1-10 will most likely stay the same for the foreseeable future.
10-60 once we get 10.0? Increase the leveling speed and add Shadlands to the pool of zones you can choose. And the new zones being 60-70.
Or
10-50, squish us down to 50 again, and add Shadowlands and make the new zone 50-60.
Or
10-50, keep shadowlands 50-60, with the new zones 60-70
