As I mentioned, it depends on how often you’re expecting to have combat encounters in your game. The accounts we’ve given are from games with what I’d consider a “normal” amount of combat, where 3 encounters in a day would be rare, most days will only have one combat encounter and there will frequently be days without combat (either spent travelling, or off-screen downtime, or plenty of social encounters but no fighting).
Your opinion isn’t wrong of course, it’s just circumstantial. If you’re playing a dungeon crawl where every room is a new combat encounter then Battle Trance is indeed a terrible feat to take, and in that situation maybe you can talk to your GM about introducing some house-rules for getting rid of Fatigue faster. We’d be happy to help them address balance with some details about what they want the game to be like.
