@CCbathwaterThe issue isn't that she's better or worse than anyone else, its that she's fully capable of turning around a fight without any real skill from the player. She just taps the res, and if they are far enough back, has the two up and going before the other team can readily push. Its not dependent on her player's skill, its just a simple button press. Granted up close she can be fairly easily stopped, but that takes away precious seconds where she is shooting at you without you shooting at her. (Grenades also take a second or two to deploy and re-equip weapons from)
She doesn't need a nerf, she needs her old kit back. The fast heals and shield were fair, because it took her out of the fight for a little bit.
