I think what they listened to was their metrics that most people quit by level 50, honestly. They probably interpreted what the fix was from partially the community though.
Its funny, at launch I thought WT2 and 3 felt pretty on point. WT4 I felt was a slogfest because what I stated. This season I felt WT4 felt great but WT2 and 3 felt like a quick waste of time. Especially WT3.
