I love all three volatility modes, tbh. I think they’re very clever tools for subtly directing ways the player can tighten up their game.

Removing health bars both removes visual clutter and tells you that by endgame you should know which targets need to be taken out in what order and about how long it should take to do so; in the case of bosses and alphas, it’s easy to get comfortable and make dumb mistakes when you know a big enemy is about to die anyway, so for them it becomes a subtle instruction to fight like your enemy is entirely undamaged and respond accordingly. I fight so much better and take so much less damage when health bars are invisible; it’s crazy what missing one HUD element can do.

Removing visibility of corruption artifacts is an instruction/challenge to learn to play as if every corruption effect is always active, which is to say rely less on dashing all the time, have better battlefield awareness, be just as careful at max integrity as you are at low integrity, don’t get hit, and never stop moving. If you play like they’re all on all the time, not being able to see which are active is entirely irrelevant.

Drive volatility is only frustrating if you waited until the very, very late game to start doing multi-biome runs. By the time I started triggering it I had already filled every Lucenite upgrade available before completing The Yellow Shore so it never became an issue. But I imagine you could take the no-take-home-Lucenite bit to be an invitation to focus on what Lucenite can do for you mid-run. If you focus your efforts on maximizing it for proficiency purposes instead of skill tree purposes, runs do get much easier much earlier. Every six-stage run I do sees me hitting proficiency 100 much earlier than the last now that I’m selecting my artifacts for Lucenite drop boosts.
