I saw some post about wes and i think they are missing the the whole point of the character, i think he is and always is gonna be the challenge character but thats not a reason to be a boring or not appealing character so i had a good idea for his skill tree that doesnt change his core as the challenge character.
My idea is simple, give wes some skills that unlocks specific task to do like "labours of heracles", for example one skill that adds the challenge to kill bee queen during summer or winter and after you are done with the task you get a reward in return, it can be like more loot from the boss or whatever klei thinks its fair for the task. Others skills could unlock easier tasks that can be done as much as you want like every time you kill 6 hounds under 3 minuts wes gets a little buff in speed for 20 seconds. Or even tasks like kill CC without using certain items and in return wes gets a perma buff of 10 extra points of health. And of course some rewards could help teamates.
I think this makes sense from a gameplay perspective because wes is the "challenge character", and it makes sense from lore perspective too, remember that wes was trying to be a hero or at least trying to help during his animation, so being the "hero" like heracles with his labours makes sense for Wes.
This idea of challanges to do list in my opinion could help Wes to be more appealing to play for intermediate and veteran people because lets be honest even for a veteran like me he is not fun to play, and its not for the challenge it is cause he is boring and tedious, but if klei gives Wes a to do list to challenge yourself with little rewards for the inconveniences even me that hates the character would think about playing with him.
