Ezreal passive VFX

I’m not super familiar with the boards so I hope this is the right place, but I was wondering why the Ezreal skins that use base VFX don’t have a passive glow on his gauntlet? Some of his other skins do which really helps with readability so I was wondering if maybe it was just overlooked when he was updated. I’m not sure if the right people will see this so any bumps and conversations are extremely helpful!
