So my second week now, warrior & rogue got 12 & 17 echoed Ephemera after running all of LFR, normal 9/9 & 3/9 Heroic. (all lfr & 9/9 normal first week.
Today I went on my hunter, picked up the quest and have 20/50
I did 9 normal 3 heroic 2 lfr bosses.
Is there a fix in the works?
They are aware of the situation.
My hunter started with 0/50 after doing normal & 3 heroic bosses I was capped20/50 after first heroic boss in just this 1 week.
My rogue & warrior have been doing full normal full lfr and first week
my rogue & warrior THiS week did full normal & 3/9 heroic + LFR
they are stuck at 12/17 (rogue / warrior )
So I’ve read through what you wrote and it seems they have no fix and are just betting on people catching up eventually 
This is absolutely sad.
That’s practically the exact opposite of their official response, though? 
They’re working on a fix as of three days ago, they just don’t have an ETA.
