Sure, and that's frustrating. I might not be intimately familiar with Bedrock, but I get it. Just hearing about some of the issues and what they can cause or lead to turns me off.
I also understand it from the perspective of other issues, because Ja has its own.
I used to be a player who would strive to play at long render distances (and for a Ja player, that means 32, which is probably nothing in Bedrock, at least prior to 1.18). Then performance debt caught up.
I used to strive to play with anti-aliasing. Then 1.7 happened. Editing the options file worked... but with its own issues. And then only until nVidia's driver updates post 373.06 happened. And then until editing the options file stopped working.
You missed my overall point. These may be issues on their own, but not at all reasons to change potion/game play balance.
Thinking they should he their fire immunity removed isn't saying they should be equal to the fire protection enchant. You're giving it a Black or White only ultimatum, when really there's a huge space of possibility between them.
And in my opinion, you're playing the fire protection enchant down a bit anyway. The fire protection enchant isn't really useless on its own. It's currently useless precisely because of fire resistance potions giving fire immunity. Without that, the fire protection enchantment suddenly becomes a bit better. Still probably not a go-to for the most efficient setup, but useful at least. Remember, the protection enchants are all mutually exclusive and therefore competing with one another, so you can't use the fact that it's not used (which is again largely because of fire resistance potions anyway) as a sign that it is useless in a vacuum. It's not.
But this isn't to say I wouldn't be opposed to some balancing/buff efforts there, too. Certain things (fire protection, projectile protection, smite to a small degree, bane of arthropods to a large degree) are between way under powered to useless. Maybe he projectile and fire protection do 50% more than they currently do? I don't know; not a numbers person but they feel near useless. Blast protection only earns its spot because of how powerful the thing is it protects against.
But I get the impression you disagree with them changing away from fire immunity at all, which is fine. Your following post explains your reasoning and I see now where the source of our disagreement comes from. I find the game too easy and find there to be too many ways to oid being penalized for mistakes. And I say this as a HUGE casual and as someone NOT what you'd call "good" at the game. I mostly play to build, and in my non-hardcore worlds I may die a lot, but it's always due to carelessness or NOT using many of the game's broken features, because if I ever try or do use them, I won't often die, and my hardcore world attempt has shown me I get far better results even while being unskilled simply if I put in a minimal amount of effort, and that's solely due to how unforgiving the game already is.
But anyway... I wasn't trying to start a discussion on if that particular potion should be changed. I just stated my preference on it in passing, but more importantly I was agreeing with what someone else said on how they are poorly named compared to what they currently do.
I did pause when considering that, but as mentioned, it has the effect of slowing you down so it's not really directly comparable.
It's also much harder to get, doesn't last as long, and still doesn't make you completely immune to certain damage types, so even without slowing you down it still would not be directly comparable to something like the fire resistance potions.
