That said, the demand is going down anyway, as you said, so they wouldn't be a viable method for long to begin with.

When people start telling everyone else money making strategies, it's because the optimal time for those strategies has passed and there's a new one that they're using now. The item upgrade system introduced in 5.1 helped a bit but I doubt it would've survived the next raid tier regardless.
