100% the blue post just said they “paused” it because “insert lie”
The truth is that the devs said they had no plans to release LFR in cata, then some kids came on crying about no LFR, so blizz then quick made a leak for LFR 10man. Then a week or 2 later they announced that it wasn’t ready. Most likely because
A. The devs didn’t actually work on LFR or want to really release.
B. They broke LFR and didn’t want to admit it.
either way they are covering something up.
