I'm disappointed that BFA is getting the WoD treatment with max level zones and are simply adding max level content to the existing 3 leveling zones for each faction, rather than adding a completely new zone for max players only.
This is only going to lead to burnout and boredom much quicker. On top of that, it is just very lazy and is a big red flag that they are desperate to rush this expansion out as soon as possible for a quick buck, no matter how much quality is compromised.
Cutting corners like this didn't work in WoD, and it won't work in BFA.
