Why is no one talking about all the new abilities?

Just got the game, but I see most of the build and tips vids on Youtube are a year old. No one even made a vid about the new cool abilities they added, like Shadow Step, where you can teleport to behind the target and insta kill them. This is just a new Ranger ability, dont even know what the new fighter and wizard abilties are. This game got written off way too early imo.
