The most comfortable and uncomfortable opponents for the Stronghold.

If you think about it, the Stronghold was designed as a race that could be played against all other races on an equal footing. For example, it's effective for Dungeon to play a rush strategy against Stronghold, and Haven can put up a good fight against Stronghold in the late game, and so on. Each race will have its own strengths and weaknesses against Stronghold. Some players find it difficult to fight against Sylvan as Stronghold, while others find it difficult to play against Haven as Stronghold. It all depends on the players.

In my opinion, a worthy opponent for Stronghold is the Dwarves, because they have good defense and runes.
