I agree with you. However, I always assumed that the ability to synchronize stations would be part of the game. The new station design and lack of grid might make that harder. Hopefully Frontier is thinking of a solution! Most of the parks I've been to have a synchronized coaster. Some of them race and some of them duel. I like building those too.
In the older RCT games I used to make a ton of money to fund park improvements by building a pair of shuttle loops that were synchronized. One of the trains would be rear-facing. It looked good, quickly paid for itself, and delivered 2 slightly different experiences. It was a win-win for scenario parks I could put it in. I think this is a less-known use of the synchronization feature. Doesn't replace a pair of full circuit synchronized coasters, but it sure does fund their construction!
