Arguably Jin'rokh Lightning Storm aswell if someone plays bad and soaks many balls in a short interval, a Healing CD won't save you there while a DA might.
Also in a 25m raid you want a mix of both damage prevention and healing cds which is why I find it silly that Palas are afraid of losing their raidspot. I find it the most optimal to have 2-3 DAs(obviously there are exceptions on fights like Megaera where you 100% stack, but that's not the case in SoO). Prot Pala brings 1 of these, then maybe you have 1 ret. But let's be honest, who stacks melees anyways? A caster is almost always better, so you need the DA from a holy pala.
I do agree though that DA should prevent physical damage too, but then Barrier needs to be buffed abit to compensate, since it requires people to stand in it while DA doesn't.
