We don't currently have plans for it to work on other players. We changed the way absorb mechanics work between Burning Crusade and Wrath of the Lich King, which caused Reflective Shield to become self cast only. It was a sacrifice worth making, and so many discipline priests told us they loved Reflective Shield that even with the stipulation that it was going to work only on themselves, they still wanted the chance to get the talent so we kept it in.
We can update the tooltip to say “priest only” though.
