You're misinterpreting.
The idea is I support, as a general rule, the attempt to evolve from early MMO design in a way that is different than how WoW did it because, as we've all whinged about for years, WoW fundamentally shifted MMO design in a way that made it worse in a number of ways. Not in every way, WoW is objectively a better game, but it made specific design choices I want to see challenged. WoW's success made it impossible for innovation in a lot of ways.
Instancing is a specific area I'm interested to see changed. Another is the idea of building a giant world initially, and instead of expanding it with expansions, just filling and shifting it. There are plenty of legitimate criticisms to the game, but I maintain that their attempt to innovate in this space isn't one of them. They can always give up and instance. That's not going to be particularly difficult, and I think they'd be well served to use instancing in some circumstances, but I want to see a fresh approach.
