Irony is, we actually
did have Shell back in 1.0,
and, in ARR and HW, Shell was actually still in the game anyway, but rolled into Protect automatically with the 'Proshell' trait, effectively making it the traditional FF spell
Wall in all but name (probably due to pragmatism - why complicate matters by providing spell bloat when players would want protection for both physical and magical attacks and just cast both spells anyway one after the other if offered both seperately?). Then when Protect became a healer role ability that was lost.
Personally I'd love to see Protect return, but I think SE has made their choice. Divine Bennison sort of replaces it at high levels anyway, but it's not completely the same (rather than just outright giving increased defence it cancels damage out to the equivelant of a 500 potency heal), so there is hope that maybe one day SE might bring it back for CNJ/WHM, but I'm not going to hold my breath.
