Multiple Strongholds

Strongholds are getting old indeed. 

Maybe if we had multiple Strongholds or similar structures that had no End Portal, but hints to help the player know about the Eyes of Ender and how to use them to find the real Stronghold with the portal.

These structures could give other hints about how to get to the End Cities too.

Basically, they would do something similar to the ruined nether portals, but they should be harder to find.

As an extra, the loot in the Strongholds could be a little better. And maybe adding new blocks or variants like a deepslate-bricks variant.
