Really nice change coming up in WoD. I never enjoyed gear being the same but with better stats the higher up in difficulty you go. It didn't feel like much of an upgrade to go from LFR>Flex>Normal>Heroic. A few points higher on each piece was nice but it was the still the same piece of gear, same name, same bonus'. Sounds like LFR will have very different sets of gear to the other difficulties:

Traditional class tier sets will no longer be available in LFR difficulty in Warlords of Draenor. You'll need to run normal, heroic, or mythic to get your hands on tier 17 gear. That doesn't mean LFR-exclusive raiders will be entirely without set bonuses. In the latest beta build, Blizzard has added some new set bonuses which are exclusive to LFR gear. These bonuses are not class specific, but are instead armor class and role specific. For example, enhancement shamans and hunters share the same set bonuses.
