The problem started with Rise, which is not well regarded with the modern MH audience. It was seen as a simplification of World, and people see Wilds as continuing down that route. Rise sold well because it sold well on the Switch(which did not have World). On console + PC it only sold like 1/3rd of Worlds numbers. It sells now based on price.
I’d imagine the Wilds expansion will take the game much closer to World to appease those people.
Wilds also had massive technical issues, especially on PC, and that also affected sales.
