This is great, thanks again @BlizzardTeam.
One thing I will say, personally, is that the Sharding idea that you brought up in the " Addressing Population Concerns in WoW Classic " Post sounds ideal for classic.
This is what Whitemane needed, and it is worth the risk! Although, as I’m sure your diligent team has talked about, this will 100% effect the economy which is why I support Sharding Personally.
(P.S. This isn’t a bad time to try this with the release of ZG and flux in economy via Rep grinding, Kudos 
)
