I really enjoy the set-piece nature of most of the combats in this game. They feel strategic and fun to me. However, I agree that in the finished game every combat shouldn't feel like that. There should be some simple, easier ones mixed in.

Overall, I'd love for the game's structure to follow this from the 5E DMG

The Adventuring Day

Assuming typical adventuring conditions and average luck, most adventuring parties can handle about six to eight medium or hard encounters in a day. If the adventure has more easy encounters, the adventurers can get through more. If it has more deadly encounters, they can handle fewer.
