I'm not sure the engine supports that sort of interaction. You'd basically have to make a fundamental change to the way LoL works on a technical level just to implement a single champion ability. We're also talking it flat out blocking an ability like True Shot Barrage, which does pop spell shields. As in, Ez casts True Shot Barrage, it hits the barrier, it ceases to exist. Again, I think the technical requirements of this ability are far too great.

I'm assuming here again, because I have no other info to go on, that you don't put the barrier down right infront of him, but rather place it using a reticle similar to Karthus or Anivia. Otherwise, its going to be very, very difficult to position usefully. Additionally, team fights are far too mobile for something which isn't the size of like Karthus' wall or even Anivia's ice wall. You can't really hide behind it for any great length of time because battles tend to wander a bit with targets.

I'd already consider those uses with his E, but honestly I also don't think it fits with the theme of a guy carrying two shields. It would make more sense of him to 'intercept' an attack by tossing his shield onto someone and having it act like a spell shield, or even better, have him physically dash to the allied champion, covering them with a spell shield ala Intercept from WoW. That would solve the issue he has with offering carry protection without saving both his R and another ability when jumping into a team fight.

Otherwise, if you blow your Q, your R, and then your W, you've got zero ways left to protect the carry except to try and anticipate spell casts going toward the carry and put that barrier up. Even then, the carry isn't going to hold still behind that barrier, they'll be constantly repositioning for a better angle to do more damage.
