Buff Assault's Adrenaline Pen

The instant heal it had during the early beta was too strong, fair enough.
Currently, it is practically useless.
So meet it halfway in the middle: Using the Adrenaline makes you immune to suppression and increases natural heal rate by 50%. (Not stacking with Frontliner's training path)
Honestly it would still probably be on the weaker side with this buff but it least it would be worth pressing the button.
