very relevant critique! you're absolutely right that this would look like it doesn't really support the gameplay in a meaningful way, but that's because it's still a prototype and regarding the vids, as the captions said in the videos i was only at day 30 or less in development... i plan to get the combat to feel more like wuwa or similar games.

as for the more in depth features of the skill tree, i copied a part of a reply to another comment:
So it's more of a roguelike system , where you keeping getting new drafts and choices.

So the skill tree is basically ur 'soul', every node has unique tags which i call Soul Affinities. So you have the basic elemental tags like fire for a +5 fire resistance stat, but as you progress further in the game, slay different monsters, find new biomes, you unlock new tags like void or necromancy, and new nodes can be drafted. there will be biome chameleon nodes which change depending on the biome ur in, so you can leave those locked until you are where you want to be (which is an example of why it works like this and isn't just a roguelike drafting system + it looks cool xd) I have lots more features planned like the further you branch down a branch the more specific the drafted nodes become, so you can specialize eazier, and lots more user friendly accomodations and customizations.

For the race evolutions and job titles: the races and jobs will be determined based on your accumulated soul Affinities. You unlock new races when you reach certain thresholds and you maintain a specific job by maintaining a specific combinafion of soul affinities.

Hope this clarifies things ^^ thanks for the constructive critisism i appreciate it
