If you haven't figured out by now that Blizzard has no plans to increase content distribution going forward I don't know what to tell you.
Things won't change in Legion, they will probably get worse.
Blizzard is milking you guys for all you're worth.
It is most obvious a few years ago they had a meeting with the execs and decided not to invest much time or resources into WoW anymore. Legion is going to be a failure of epic proportions.
