Invalidates what where for whom exactly? Anyone who is half-serious about raiding does normal and heroic progression on week1. The token gear will have zero impact on that. It is a long term catch-up. If a person would decide to not raid because he can get same gear somewhere down the line - that’s on him, really. A fair choice, that has nothing to do with token gear. I personally decided to skip dazaralor threadmill because the gear will get invalidated in 8.2, should they not release more raid tier so the raids don’t get invalidated.
If token gear “invalidates” the raid to the point where one does not have to farm heroic raid for 4 months to get 430 gear and instead can do it in 2 with a combination of two - i’m All up for it. As any sensible person will be.
