Oh hey, I am qualified to talk about this!
Notoriety: I don’t see this one as a problem. You can’t just go around committing crimes, and expect no consequences. For being a criminal, you gain access to two entire shipwright islands, can bounty hunt every npc (unlike fame players, who can’t bounty hunt hero and gravy member npcs), get cargo for free for ds runs (with the new supplies mechanic, the free cargo is redundant, but it is still an advantage) and you get the cooler faction to buy stuff from between Proxy and Brotherhood.
Water Poisoning: In its current state - it is awful. Can’t defend the rng lethal damage with no warning whatsoever. But, it can be made into something better.
This one’s kinda meh, but I heard some people wanted to keep it in some way. In my suggestion, I made dirt appear only while you are in combat, and completely disappear about 5 seconds after exiting it. Oh, and also you can put an armour piece into a cauldron with some rock salt to get it visually dirty permanently, if you like it.
