Are you mistaken? The weapon quite literally is unchanged EXCEPT for on classes that aren’t even suppose to be using them at their level, as seen by the fact they cant even use the first skill on the weapon.
I’m not even going to bother adressing any of the other ramble points you said aswell, since there’s no point. Once savants actually unlock the first skill on the shield, they’ll be able to use it, and that goes for all other classes too.
