Makarov is definitely much stronger now than when Precht handed over Fairy Tail to him. And I'm pretty sure he was much older then than Gildarts is now. So Gildarts being past his prime is just your assumption. Cannot be proved to be true or false unless we actually see the guy. ... I so want Gildarts to return! Dammit, now I've lost interest in everybody and just want him to return! T_T

Warrod and Hyberion not being human is also just an assumption for now. Unless you're referring to Ooba's statement, in which case you might want to read about.
