i don't know how they do it there, but wouldn't it be easy making a new or copypasted shield without any models or a transparent one at that? i don't believe they won't do it from what i read.. can't use shield lob/bash you say? i could argue that the shield is invisible.. but still solid..

plus shield lob only throws energy that's shaped like a shield.. the shield does not exactly leave your arm nor does it have any returning animations..

if they would like to compromise.. i'd like to see Cross-shaped shields or Rosaries/Rosary beads like the idea above.. or just a shield that says HOLY SHIELD
