It encourages you not to rely on easy mode! Because it is now locked behind a very time-consuming process, it incentivizes players to actually defeat foes for experience instead of fleeing all the time!
To some degree, I do understand that. It feels a lot more rewarding to take down difficult foes (which is why I wish there was actually an implemented Hard Mode), but from an accessibility standpoint, it just feels weird having the Easy Modes require dying multiple times on the same fight.
I have one friend who genuinely struggled with enemy encounters and boss fights, and it ended up bringing down their experience a lot. I don't agree with how said person handled it at all, but I feel like that experience might not have been as bad if they could've just had Easy Mode on.
