Update Please – Breeding Guide for Dragon City Review

This information is really old, please update it so the app can tell people accurate information, for instance the poo dragon is only able to be bred with a legendary and one of the other elements of it (dark, terra, etc) and it says I need just hybrid dragons with the same elements? Please update, this app was so useful until this so please
