So in 9.1 you'll be able to upgrade gear to heroic iLvls by doing casual content. It has been likened to benthic gear so most presumably a limited resource/currency that will allow you to slowly work on upgrading your gear by doing daily quests and/or world quests.
Hopefully you can earn the currency from daily heroics and LFR as well in order to breathe some life in to those forms of casual content.
Thoughts? It seems as though Blizzard have listened to the feedback from all the casuals who quit shadowlands early on.
