Couple brief thoughts.
The vitamin change coming.. We'll see what happens with it. I guess that's all that can be said for now, because prior to the notice of this patch, they were a complete disaster. You'd starve faster than your vitamins would drop so if you weren't careful down to the single piece of meat, you would give yourself a surplus just to keep from starvation.
The new skill tree. I don't think anyone disagrees that it needed to be updated, every skill costing 1 point wouldn't sustain outside of testing. Got it. But I feel like this change went overboard. I understand wanting individuals to specialize in a single skill tree to provide a unique existence among the tribe, but for anyone trying to play solo or in a small group, this change made the game damn near unplayable. It just needs some refinement, ease up a bit on either the skill cost, or give more skill points per level (a multiplicative curve possibly, so the early levels aren't broken either?). I think a fair starting point would be to give enough that at level 50, a player can specialize in 3-4 skill trees, instead of 1. It would give solo players and small tribes a more well-rounded crew, without breaking mega tribes - because honestly, 1 skill tree or 20, mega tribes will always have someone around capable of any tree. 3-4 would allow for players to pick 1 or 2 of the lesser sought-after trees without impacting their play as much. For example, one player could be your builder, and specialize in both home and ship construction, and still be able to pick up captaining and piracy - while another could be your tribe's blacksmith and work the tribes' metal into melee and ranged weapons, in addition to being an armorer.
The predators, ghost ships and resources you've already mentioned about changes coming tonight/tomorrow, so we'll see how those fare.
All in all, just my initial thoughts so far on some of the patches. Thanks for the read
