The CD is necessary to be short for ret/prot, so you can't nerf that. The amount of healing it prevents is about as crippling as you can get. Being dispellable disproportionately weakens it in some areas, and makes it stronger in others. (Like against druids, or if you have a partner that is tough enough to totally prevent a kill while you LoS)
Don't know what else you expect, there isn't much more to nerf.
the fact is Divine Plea is retardedly OP for holy paladins. Anything that isn't a nerf is a buff I don't care what you say. It STILL needs to be nerfed.
Retarded comment considering that you haven't played against these changes.
