He is meant to be simple and easy to understand. No complex mechanics. No major gameplay changes.
So much of what i see people suggest is over the top, and huge. If these were added, it would ruin the point and niche of Wilson as a character. He shouldnt have exclusive items.
I am really fond of Wilson's simpleness. The other characters nowdays are often too overwhelming or feature bloated. Wilson lets me focus on the world's tools rather than my character's tools, and the focus on the character tools nowdays is what i believe to be a big flaw with modern dst's characters.
I do believe Wilson's skilltree needs changed, its still bad, but mostly just:
▪Better transmutation rates. (3 rot for 1 manure, 1 manure for 2 rot ect)
▪More practical transmutations. (Most are kinda useless and rarely used, add more like the meat one)
▪Let light skills work on all light sources, condense them a little and add new abilities for Wilson to apply his light buffs to campfires and dwarf stars.
▪Condense beard skills.
▪More affinity transmutations. E.g transmute butterflies to moon moths, transmute petals to dark petals.
Wilson should never have any exclusive items, or over the top buffs. He should just improve existing item mechanics using his science knowledge, and have things like transmutations.
Turning the default character into another insane new character would just shrink the cast diversity and options. His current skilltree adds some extra gameplay to him to make him at least have a few new strategies and benifits to the team rather than being a burden.
