I'll start this by saying that I can't stand the idea of LFR. I don't believe that it is interesting in any way shape or form. I believe that it is neither engaging, nor conducive to any kind of personal enjoyment, for me. I do acknowledge that it is here to say and how a vast majority of the playerbase experiences the content
The reason that high end raiders dislike it is primarily two-fold (there are arguments for a third, but I will deal with two) in that: 1) they are strongly incentived to participate in it and 2) it diminishes the sentimental value of getting the kill on whatever difficulty you aspire to complete when Johnny No-Hands and Kelly Keyboard-Turner's blind cats can kill it while maintaining around 8% of optimal DPS/HPS/tankingpersecond.
The second has been addressed by Blizzard and is why we have wings released on a delayed schedule for LFR. Sounds good. The third argument that I mentioned is that new players will see the herp-derp mode, feel like they've completed the game, and decide they're done until the new stuff.
The former point, I believe, can be remedied by having a loot lockout that is solely for LFR. If you complete a boss on LFR then you cannot receive anything from that boss in any other difficulty throughout the reset. The same goes vice versa for the other difficulties meaning that if a boss is killed on Heroic difficulty there is nothing to be gained from killing it on LFR difficulty.
There would then be no reason for anyone who does not wish to run LFR to feel like they have to, and LFR people would finally be free of all the elitist-scum who come into their LFR. They'd be left to their own devices to progress through the raid at whatever speed that randomly assigned group can muster.
TL;DR - Give LFR its own loot lockout. You can either get loot from LFR or the other three difficulties. Higher end raiders won't have to subject themselves to LFR for any kind of gain, and LFR raiders wont have to get bitched at for trying to experience the game in a way that suits them
Flame on if you disagree. I might have a terrible idea and that's fine, but I feel that this would satisfy both the LFR crowd and the anti-LFR crowd. Thoughts?
