Tactics for the Stronghold.

Why do you dislike playing on 200% difficulty? And why shouldn't you build a Tower? Are you not playing as Orcs? Having bears on the first week is an overkill! Although, it depends on the difficulty level!

When playing on 200% difficulty, there is a minimum program and a normal development path.
The minimum program for the first week is to get birds in the Stronghold. A normal option is to get units 1, 2, 5, and 7, depending on what's available. You need to deploy bears. Orcs are good troops, but they have several significant drawbacks compared to bears:
1. They are slow. And the hero moves slowly on the map with them. And many enemy troops move before them.
2. They have a penalty in melee combat. So, when taking Hive castles, they usually have a very hard time.
3. Without magical support in the form of speed boosts/slows, some difficulties may arise when taking Griffin Conservatories. Orcs are not so easily cornered.
4. In Utopia, Orcs die quite ingloriously.
5. For the Stronghold on 200%, Gurnisson, Crag Hack, Dessa, and Gundula are good choices. There isn't a hero specializing in Orcs among the first four...

In light of the above, it is recommended to reconsider the approach to building in the first week and try to deploy bears. And if you want to breed Orcs, in my opinion, if there are no ambushes and no hero specializing in them, it is better to build a Castle, because you will need a double increase in birds, and the hero moves quickly with them.
