Few thoughts:
Anemia
The debuff w/ regard to Worth gain from this is not even close to making this viable. Keep in mind that 1.5x == 150% percent-wise, which means that someone with Bleed would take more than twice the damage with this Return trait on. Considering how humans have default 100 health, and not everyone who joins our server has over 100 health, and given how easily it is for zombies to go Blood Warden + Headcrab combo, this is something no one's going to get.
Fix: +25 Worth / "Bleed" status effect now permanently reduces your max health by 3 points/ game tick, or 3 points/ second.
Hemophilia
This is broken and game-breaking, on top of making Blood Warden useless because Blood Warden does this already. We might as well remove Blood Warden if this becomes a selectable Return trait, which will never happen. The proposed re-name for this trait also doesn't make sense for what this trait does.
Fix: keep name / +15 Worth / "Bleed" lasts 50% longer and slows by 15% for the duration.
Insecure
Not an appropriate trait name for what this trait actually does, nor should this trait be added; it's just a more-complicated Palsy clone. Not necessary to add, and a poor excuse to give humans more worth for what it does.
Fix: don't add to game.
Bad Shot
Like Insecure, this trait is a Palsy clone. Not necessary to add to the game because it would be redundant and act as a poor excuse for humans to get more starting Worth.
Fix: don't add to game.
Juggernaut (provided by Old Bill)
Essentially useless not only for how much it costs, but for what humans get out of it. Reminder that humans die very fast because they have 100 default health, and zombies inflict approx. 32-35 damage/ hit.
Humans with this trait being unable to pick-up nor receive weapons doesn't make any sense. No thanks.
This trait could be added to make things more fun and interesting, but there are much better ways to do that than take this route. Sorry, this is a very useless trait for what it does, and no one's going to get it unless it provided some benefit that's worthwhile.
Fix: -70 Worth / 70% damage resistance, can't be slowed, attack 15% faster, but can only buy melee weapons and utility tools.
