The failure is still in the Shield design and not the Tokens, having Redirect helps a single issue with the side shields being so weak, but does nothing to attacks on the front or rear. And, as much as we want to get a front and side shot off in a single volley, that can lead to more exposure of those glass shields on the side versus return fire.
