This is the first MMORPG I have ever played that had more than 10 buttons involved and honestly, back then, it stressed me out seeing people’s interface for the first time with all their skills spread across hot bars on their screens lol. It’s definitely possible for 10 buttons or less to be fun. The SMN overhaul might be a testament to that with how few buttons we will have in Endwalker. It just has to be done right, along with encounters in this game become more engaging outside of endgame.
