This is probably a hot take, but...

I personally think the gauntlet style Pantheons are a bad design choice.

I'm on Pantheon 4 and I can now consistently clear the gauntlet to reach Pure Vessel. The problem is that I want to learn Pure Vessel's fight, but I can't do it without having to clear the gauntlet each time (which takes ~15-20 mins for me). It feels like a massive waste of time just to get one practice/attempt in. I can do Soul Tyrant hitless now, so I'm almost always going into the fight with full health and soul anyways, so it's just annoying to have to run the whole gauntlet each time.

I know some of you might suggest learning the fight via YouTube, but it's a whole different experience learning by watching versus by doing. The Hollow Knight is also not a good way to practice because there are some attacks unique to the Pure Vessel, not to mention just spamming attack with Quick Slash and Unbreakable Strength easily kills Hollow Knight but won't work on Pure Vessel. And Pure Vessel is faster.

Definitely a bit of a rant, but I had to get it out there.
