So many bad takes I don't have all the time to bother quoting.
But, LFR was introduced on Blizzards end to justify the enormous expense making raids cost. When only seeing 15% or less of total players stepping inside, 3% in the case of Naxx40, there was literally no justification for raids.
For the players, it was introduced so those who wanted to see the story/content could do so without dedicating themselves to a raiding guild and their demands and time commitments.
That is it. It was never designed ad a means to get cheap or free epics. It was never designed as a stepping stone into organized raiding.
Those who don't need to use it to can just ignore it. You know, like most functioning people do when there is something around they are not interested in.
LFR doesn't take away from higher levels of raiding. I raid mythic(previously heroic) and LFR never bothered me. I never felt I had to run it to get my tier set or trinkets faster, nor have I ever been "forced" to run LFR for gear. If you feel you need to do that, that is your problem. If your guild requires it, find a less toxic guild or do what you are expected to to be competitive. If you were required to run normal instead of LFR would you be here asking for the removal of normal?
As for the stepping stone argument, the people LFR mostly targets, are those who would never raid in the first place. They were not raiding before LFR. Removing it wouldn't have them suddenly start PuGging normal.
But really all these threads are disingenuous. They are never about the betterment of the game. It's a big I don't like the thing so Blizzard should remove it.
Frankly these threads never go anywhere, never bring up anything new, and should be a forbidden topic. Considering it's just an attempt to troll those that use LFR.
