One of the big changes of Shadowlands was Chromie Time and the Level Squish.
You would be able to play through a whole expansion rather than having to leave it half way through. Or so it seemed. After you reach Level 50 you get locked out of Chromie Time and the scaling changes back to normal which means you one shot everything in your way.
This whole system seems flawed and pointless because to play through a whole expansion I would have to lock xp gains at Level 49 to stay in Chromie time. Or just not use it at all since the zones already scale and I can lock xp at any level I want. Blizz should either change the leveling speed to be slower or give you an option to stay in Chromie Time when you reach level 50.
