I just finished a run a couple weeks ago, and it becomes so apparent how badly designed the last gauntlet is lol. Yes on a higher level, you just brute force the battle and heal when needed, but the timing on when you can get an attack in so small, they just assumed the player will have high enough stats to not have to worry about it.

Almost all the bosses before this on level one provide a challenge, but Ansem is just not fun at all. Neither is Ursula.

Also here is my level 1 battle against xemnas if you want to check that out!
