Yeah, I don't think he's entirely useless or anything but I do feel like they dropped the ball on poor Garrett by not giving his awakened form a global support passive--a small version of Aisha's HP boost would have been nice, for example. I say this beause he's in this awkward position of having stats that scream "Off-tank!" but it's actually Bernice who gets to buff Gellius or Deine just by standing around and looking pretty.
