They really have more or less removed flight. It keeps getting the pathfinder bullshit and blizzard, in their limited wisdom has worked out that if they make getting it a long and pointlessly drawn out affair fewer and fewer people will bother. Meaning they can slowly push it back further and eventually drop it entirely.
Pathfinder is not a middle ground. Blizzard is trying to ween us off flight since throwing a tantrum about it and pulling it didn't work
