I think LFR should be converted into a tutorial or story mode experience. Where you still have the same 20 players except also have a NPC(s) assist the players during the raid and boss encounters…
For Example if Ny’alotha had this, we could have had Magni, Wrathion, or random 8.3 significant lore characters of the Horde and Alliance fighting along side the real players, and these NPCs can serve as guides, and even yell out instruction/advice and what to do during boss encounters and between boss fights as we clear trash and before the boss pull, could tell stories/lore that’s significant or applicable to the raid.
And the way they can help players during boss encounters for example: if a boss is casting a deadly spell that the raid needs to move away from, the NPC(s) could simply yell out, “RUN AWAY!” and runs away for players to follow to safety, or times when the raid needs to focus and dps down the boss, they can charge straight into the boss and yell “ATTACK!!! TAKE DOWN THIS MONSTER!”…
I think this would be cool and make LFR more of an interactive and lore filled experience. Also I believe it can help out with the completely clueless casual, new players, and first time raiders who have zero idea of what to do by providing them simple, easy to follow instructions during the encounter itself (especially since it’s rare that any of these players look up any guide/tutorial/video on their own).
LFR has always been picked on or viewed as the bane of World of Warcraft, as players seem to hate it because either it’s viewed as way too casual friendly, requires zero skill to do, has heavily nerfed fights, promotes bad player habits and gameplay, etc.
Then the rare times when it isn’t nerfed to the ground and requires players to have a bare minimum of skill or actually read the dungeon journal or whatever (i.e. N’Zoth), players then now complain that it’s too hard and needs to be nerfed due to the sheer amount of clueless players who have no idea of what to do that end up ruining the experience for everyone.
Anyways long story short, LFR is a difficulty that isn’t for those committed to raiding, not for the type who look up guides, but rather chiefly for those who run it to just gear up their characters a bit, have no time for real raids, new players, or simply for those who want to complete the raiding kill quest in their quest logs. However issues arise often in LFR as a result of the lack of knowledge the average LFR raider has and their lack of know how so this often leads to many wipes, causes many players to quit thus forcing the people who stayed to wait over and over again for the group to refill and worse of all, potentially lead to the group falling apart completely. So this is where revamping LFR into a NPC assisted guided tour can be a good idea imo.
-edit-
Also an idea, I think that having up to three or four NPCs to tag along with the raid (variable depending on the encounter) that are specific to each role (Tank, Healer, DPS (melee/ranged), where for example the DPS NPC which only the DPS players see, follow around and attack what they are attacking, and see their messages. One that only the healers see and suggest when they should be focusing heals on the tank or raid or suggest using a healing CD, and a tank NPC which only the tanks see and lets them know when to swap threat or suggest when to pop a defensive cd…
Either these NPCs can either indirectly hint at players or directly tell players directly what to do through their comments or remarks during the encounter:
For example for the tanking NPC:
If the NPCs gave Direct commands: “Use a defensive! this beast’s attacks are starting to hurt!”
If the NPCs gave Indirect hints to figure out: "Ouch! this beast’s attacks are starting to hurt!
^Personally, I think the indirect method is best, as it’s as not immersion breaking and doesn’t just tell players what to do but just provides enough of a clue for players to pick up on and figure out through repetition/experience what they mean.
