IIRC, it's the opposite.

Bastion: PTR
They nerfed sentry but made recon much better. They made the repair so much better as well.

D.Va: PTR
Buffed Matrix. Looks like it's gonna make roadhog hook less useful ;-;.

Mercy: PTR
Buffed Resurrect. Made it so that you can't target zenyatta during his ult with the staff because it does nothing. Added sensitivity customizations for the abilities.

Ana: Last Patch
Nerfed grenade.

Roadhog: Last Patch
Made hook not be able to pull people through the walls, but actually made it pull them in front of you instead of 4 feet above you randomly.
