I don't think that Eagles should be rideable for long, or at a distance far from their eyries. The only person who ever actually rode an Eagle far away from their homes (realistically, the only person ever to ride a Great Eagle at all) was Gandalf. The player is not Gandalf, or a Maiar, or an Istari, just a human.

Eagles should certainly never be tameable. They owe allegiance to Gwaihir and Manwë alone, and similarly to Shadowfax, they will only let you ride if they want to and Gwaihir has spared them. No proud Eagle would deign to constantly serve a Man, and come at his beck and call.
