I will say; I like Gringotts, and I like Transformers. They are energetic and engaging, filled with cool effects and fun motion experiences. Whenever I get off one of them, I leave almost ...surprised?, by how much fun I had? They are enjoyable attractions in a lot of ways, and so is Battle.
But the issue comes from missed potential, and from how much better similar experiences are in other nearby parks. Battle is not as good as Spider-Man or Forbidden Journey, and Unchained laps all of them by a mile. Why spend 120 minutes waiting in line for Battle when you can loop Unchained at a 15 minute wait at multiple points in your Epic day?
Gringotts, Transformers, and Battle are all solid rides, and are surprisingly enjoyable once you're back at unload, but they don't get me excited to ride. They are repetitive, and they have some logistics issues, and they just don't hit the bar set by attractions built way, wayyy before them.
