Let me literally take the same information from the video and present it to you the way you did everything else:
Specter is a shadow-attuned defender of his homeland, using magic borrowed from the depths of darkness to tether their soul to anchor your physical form in this plane. Stalking through the shadows, the Specter is able to transport themselves through the battlefield keeping their allies at the brink of life with the sheer will drawn from their very soul.
People need to stop letting their high expectations devolve into confirmation bias that they didn't just hear the same information in the same way as everything else that they are using as examples. This is some serious smol-brain, russian facebook disinformation tactics people are absorbing to shit on video games they actually like. Dear god what insanity are people using to argue against things they actually hate?
