Looking at the stats post nerf best case scenario you hit a hero every 9s and get 40 health. Compare that to extra regen where you’d get 27 health in that same time (+3 regen).

If you hit anything but a hero though you’re only getting 15 and if you don’t hit anything you get 0. Still seems pretty solid post nerf now that I look at it if you’re gonna be active but you need to be hitting heros most of the time to make it worth it from a pure regen standpoint.

The bullet shield is a good plus early and the weapon damage is probably a bit more valuable now that every hero took a nerf but it still probably depends on what your build has less demand on gun or vitality items
