On the PTR in both Try Mode and an AI match Ana’s new talent at level 1 Contact Healing does not give additional healing when a Hero (Allied or Enemy) is in the bonus range from her level 7 talent Anti-Healer.
On live her talent Grenade Calibration on level 1 (with the 20 hit quest complete) and her level 16 talent Contact Healing increases the heal for all Allied Heroes in the expanded circle as well as all Enemy Heroes in the smaller circle (this was done in Try Mode but I’m pretty sure it works that way in a real game as well).
