So I guess they do realize Shadowkeep wont be their most popular DLC, but they are using it as a base to build whatever they are building for Destiny 2 in the future.
That seems acceptable.
What I dont agree with, is saying that Forsaken broke a lot of bones on D2, when it was basically the DLC that "saved" the game, I hope they dont try to approach D2Y1 gameplay style again with everything being slow as heck (which I doubt is whate they are going for), because it will be controversial to say the least.
They need to mesh the best of Y1 with the best of Y2 and hope it ends up being a decent formula.
I wouldn't say that "breaking bones" is a negative thing. It's more a reference to making deep changes to the game that affect a lot of things and usually requires a lot of work under the hood. Adjusting the weapon slots in Forsaken was "breaking bones" of loadout creation, but I think...hope most players would agree it was a positive change.
