I agree with you here, Zigûr. It may have also been because both states were the main opponents of Sauron. The rulers of both, and in particular Gondor, would have been interested in people offering practical help, rather than those who kept mostly to themselves.

While there may have been those in Gondor who acknowledged the influence of Elvish culture on them, and respected what Elves had done in the past, they might (like Denethor II) have regarded them as fallen far from their past glories, and being irrelevant players in the present geopolitical situation.

One could perhaps blame Elrond and Galadriel somewhat, for not offering the rulers of Gondor and Rohan regular advice and intelligence reports.
