Take out multiple difficultieswont happenEverything on same lockoutwont happen and wont completely fix it . If they did one difficulty per raid , made the first half heroic difficult and second half mythic difficult . You also have a 10 or 5 man dungeon similar to Kara at the start of the expansion for normal difficulty , also has a que raid finder difficulty . Then after every tier is over , everything gets tuned down one difficulty . After next tier First raid is now normal first half , heroic second half . New raid is heroic first half , mythic second half . The smaller dungeon or raid is now able to que for both . Patch after that second tierthat . 1 . 5 style patch First raid can now get LFR . This way it has something for everyone . Everyone will also eventually be able to see all the content in the expansion but in a slower manner . This will bring longevity to the content .
