Don’t get me wrong, it’s good to see gold toughness being targeted as a problem and being nerfed, but I don’t believe this is the right way to go about it. The issue moreso lies in how gold toughness works mechanically, rather than the rate at which active abilities grant it.
Gold toughness currently nullifies ALL damage you take (that doesn’t just bypass toughness in the first place), which makes it really overpowering and cheap. There’s a lot of stuff designed to effectively bypass toughness and hit you for a lot of damage (or just outright instakill you) that gold toughness just ignores - crusher/mauler overheads, plasma gunner shots, snipers, poxbursters.
I think the 10s nerf is probably fine as is but I believe the effective invincibility from gold toughness needs to be removed. Darktide’s most threatening enemies shouldn’t cease to be a threat.
