You can't do that though because the rewards are the same. You are asking them to make two copies of everything and allow for solo play as a group. That is silly. It already is up to the individual player to survive an encounter. Removing the need for tanks and healers in M+ is a fundamental change to how the combat in the game works. Why join a group and change group play if what you really are looking for is a 100% solo experience?
You already have to care about not standing in fire. You are already supposed to care about doing the mechanics of the encounters. This sounds like a you problem. You don't care so it has to be the system that is wrong rather then you being wrong. You lack the personal accountability you want the game to force upon you. Lol.
Right. Because the players over the years did not want a normal difficulty LFR. So it was made easier to accomplish because people don't want to play it the way you think they do.No, a bad implementation does that, where choreographed gameplay is watered down to nothing.
