I’m not affiliated with him in any way but he just puts this into words better than I could…
Talents are a core mechanic to customize your experience in this game and not a single one should just be a complete waste of a point.
I have a few reservations for some that are called bad in the video, it’s a matter of preference for some stuff. But certain talents aren’t just bad, or mediocre, or too niche ; they’re bad even if you build for them, and that’s a noobtrap. It’s detrimental to the average player’s enjoyment of the game (and their teammates).
