The Royal Guard did so much in the past years. They were so useful in the Changeling invasion of Canterlot. They were able to hold off Discord and convert him into a good hearted spirit. The Guard aided the Crystal Empire to defeat the shadowy tyrant of Sombra. This is what the Guards wish they did, however, their job was taken by the elements of harmony and the Royal Guards were reduced to uselessness. The Guard ponies were nothing but maids in armor. Change must happen and the Royal Guard shall get one even if they will be baptized by fire and blood.
