Blizzard said they won't have another Will of Unbinding in Pandaria (as in an LFR item better than all other trinkets other than itself in other versions). That said I am pretty confindent.
But for the vast majority of raiders running LFR was not a choice. Well, it was a choice compareable to enchanting your gear. You can CHOOSE not to enchant your gear (maybe for financial reasons), but people will notice and judge you.
