Sniper

The heal given to Ballistic Shield by Defensive Safeguards has been reduced from 3% to 1% of maximum health per second while under Ballistic Shield
DevNotes: The Sniper’s defensive cooldowns were too strong, so we reduced the effectiveness of Defensive Safeguards.

Virulence

Lethal Purpose now restores 1 energy each time a poison effect deals damage, instead of 2 energy each time a poison effect deals critical damage

Operative
Lethality

Lethal Purpose now restores 1 energy each time a poison effect deals damage, instead of 2 energy each time a poison effect deals critical damage
DevNotes: We changed Lethal Purpose to smooth out energy regain and provide better resource management for Lethality Operatives, and lower their reliance on the Critical Rating stat.

Medicine

Surgical Steadiness now grants Unshakable for 4 seconds of interrupt immunity whenever Exfiltrate is put on cooldown
DevNotes: We felt the Medicine Operative didn’t have enough defensive options in relation to the other healers, so we gave them the ability to apply Unshakeable to themselves after using Exfiltrate.
—
Mercenary

Trauma Regulators now heals for 4% per stack instead of 5% and stacks 10 times instead of 15
The heal from Kolto Overload given by Kolto Surge can only heal the Mercenary up to 60% of their maximum health instead of 70%
Trauma Regulators is a now a Heroic utility and Kolto Surge is now a Legendary utility
DevNotes: The Mercenary’s defensive options were too good, so we reduced the effectiveness of Trauma Regulators and Kolto Surge.
—
Innovative Ordnance

Fusion Missile and Explosive Dart now spread both Incendiary Missile’s burn and Serrated Shot’s bleed effects
DevNotes: Innovative Ordnance seemed to have some difficulty spreading their damage over time effects, so we altered Fusion Missile and Explosive Dart to both spread each damage over time effect.
—
Powertech

In addition to its other effects, the Hitman utility now reduces the damage taken from area of effect attacks by 30% for the Pyrotech and Advanced Prototype disciplines, and reduces the damage taken while stunned by 30% for the Shield Tech discipline
Advanced Prototype

Stabilized Armor has been replaced by Prototype Armor, which increases damage reduction by 2% for 15 seconds each time you are dealt critical damage, stacking up to 3 times.
DevNotes: We felt that Pyrotech Powertechs lacked the same defensive effectiveness as Advanced Prototype Powertechs, so we moved the protection against area of effect attacks from the Advanced Prototype discipline to a utility available for both disciplines. To fill the void, we gave Advanced Prototype the Prototype Armor passive, a new ability that replaces Stabilized Armor. Finally, we gave Shield Techs that take the Hitman utility some protection against damage while stunned.
