The issue is not it being tied to Normal or Higher, which we have stated MANY times.
The issue is they KNEW the achievement said “any difficulty” for the PAST THREE MONTHS.
And now, instead of addressing this, they stealth changed the achievement TODAY, the DAY BEFORE THE SEASON STARTS to say Normal or Higher.
This is EXTREMELY unacceptable, especially with zero communication on the matter.
They NEED to fix this, period.
Again, if a store advertises the wrong price, they honor it because they know if they lose customers over it, it’s a bad deal for everyone.
Blizzard only has ONE CORRECT COURSE OF ACTION right now, and it’s to allow LFR to get it, and be more mindful of achievements they add in the future to make sure they clarify Normal or Higher.
