Cause I feel like there's no need of a tank when it comes to this game.External link →
Wasn't the shield supposed to pull aggro? I've personally never seen it be effective but I remember reading about it and iirc you made a video about it.
They did add some aggro to guard, but only while guard is active. It's barely noticeable and doesn't affect bosses. It helps a little with crowd control but can't be considered a taunt
