How would you have gone about more successfully toppling Sauron ?

[Eomer of the Rohirrim]

One, quite obvious, way he could have written it would have had the good guys win in battle. He'd probably have to invoke some other semi-mythical kingdom from the far east or whatever to come to Gondor's aid, because Mordor had such strength in numbers. Aragorn, of course, would slay Sauron on the field. Then, during the quarrel over the spoils, the Hobbits and Gandalf would steal away with the Ring — the Arkenstone manouver — and destroy it, saving the good guys from themselves.

This might actually appeal to those who love nothing better than the might of battle (though I think it would somewhat undermine the status of Sauron as this beasting, all-powerful Dark Lord).
