This honestly is the mistake imo. They ARE forcing people into them.
If I really wanted too I could probably raid and do mythic just fine but I'd rather not. Lfr was one reason I came back I had planned to stay very casual this time round and hit shit up as I wanted instead blizzard is forcing people into both to be able to see more of the story/world.
At least SE is start enough to in 3-6 months(2 patches) make the old raid tier doable in a Lfr esque way(normal/mythic since no hard mode but quealbe) with say a buff if you die after 5 minutes..
It let's everyone get a go if they want it.
