Edit: This is not meant to be "qq" or anti-LFR. I've got no problems with it, I'm certainly not complaining, I'm just genuinely curious.
With Normal mode being completely cross-server compatible, along with how easy it is to use the current iteration of the group finder tool, does LFR really fill a necessary role in the game these days? In terms of being a no effort way to click a button and join a raid, the group finder pretty much fills that slot on its own; on both fronts you have to select the raid you want to run, and in group finder you can even have a bit of control over what groups you want to join. Unless the content is extremely dated there's usually not trouble finding a group, and when it comes to Normal mode people generally aren't terribly elitist in terms of item level requirements (although I'm aware it does happen).
I get that LFR is still the sort of "click and forget" thing that people want, a zero-effort way to queue up without making the slightest selection, but outside of "it's easier to get in" is there really any game-wide benefit to it at this point? Do we really need to spend extra development time tuning every single encounter for that additional difficulty level? Because that's all LFR is at this point; an easier difficulty. The method of queuing for it seems irrelevant now with the ease of the LFG tool.
So, while not saying there are no pros/cons to LFR vs the LFG tool, can we really still argue that it's something the game needs? It feels like we still have it simply because it's already there; why remove something that's been there for ages any people are used to? What if some players only use LFR and won't know what to do without it? Even considering that, there could always be some LFG tool improvements helping guide players towards the raid of their choice. So, again, are there enough pros to LFR to make it worthwhile at a time where finding a Normal-mode run is just as easy and, frankly, usually faster? Are we keeping it around simply for nostalgia's sake, or are there players that are genuinely incapable of completing Normal-mode that would be flat-out unable to see raid content if this lower difficulty tier were removed?
