If you want to use an off realm in cardia you'll need his sync (unless you already have an in realm full break counter) but he's still good for elemental bosses without it (well as long as you also have his glint+ for overwrite aegis as well.)
Orran's also better for physical teams because of his hero ability being the only other source of non-soul break physical quick cast besides Edward's HA. He also has bard for Ode to Victory and his BSB is a crit damage boost. And unlike Yuna and Mog he's not bothered by anti heal since his awakening uses HP stock.
