ACR has the ability to use a brush to finesse a graduated filter. LR doesn't.
Why? According to the team: "As a matter of policy, we cannot add features to Lightroom dot releases."
But part of Creative Cloud membership is "ongoing updates and upgrades when they become available". This is the pitch of CC. CC was to overcome the "no new features in dot releases" BS. All of the other apps do it, and we're to believe only the LR team can't? Nonsense. I'm a subscriber for the reason that we are promised that we don't have to wait for full version number releases. Listen to Adobe's evangelists...it's what they're promising.
What's the real story?
