I don't.
That's what ECMO3 described. They specifically said, "By level 5 or so I am generally leaving town with about 30 potions of healing, more if you have enough gold and a bag of holding or something to carry them in."
They were describing being able to buy 30 per character. That's 120-150 potions.
I was confused because a 5th level cleric has 9 spell slots that aren't all dedicated to healing. A party of five has 25 hit dice available for healing plus potions plus whatnot.
IME the spells are the smaller part of the healing.
I find 7-8 healing potions each to be a high number but reasonably achievable if the players are trying to do that. I find that martials carry more healing potions than other classes, though.
Stacks of healing potions is more MMORPG than TTRPG in my experience.
Pretty big if, there. Certainly not going to be representative of most campaigns, nor even a mere plurality of campaigns.
And yet "there isn't anyone here who can make healing potions" is both (a) something I have heard multiple times, and (b) explicitly supported by the DMG text, as quoted. Are you disputing what the DMG text says?
Both cases still depend on the (very big) if that the group is using that system.
A group not using the options available isn't an issue with the options not being available. That's on the group ignoring those options.
Do you have statistics on how many groups are or are not using bastions? Strongholds have been a part of the game consistently and bastions only define benefits a bit better. We should probably discuss them more instead of dismissing them.
They didn't say per PC. 1500gp at 5th level is to unusual.
I don't sell potions in those quantities usually they find a few or buy a small number.
I don't sell potions in those quantities either, or buy them in those quantities because I haven't had a DM who sells them like that either.
IMO. The times martials may need the casters goes far beyond healing. A far more common scenario is a need for AOE damage or AOE control.
That's 100% true. The time the casters are shining is against numbers of opponents. It's a bit beside the point I was arguing where martial characters are reliant on healing, or even status effects, from casters.
The trip, push, move method of avoiding damage is pretty useful one-on-one, and stunning fist is still a thing. Martial classes have status effects built into weapon mastery and class / subclass features. Martial classes have healing from hit dice, potions, feats, and built into class / subclass features.
The argument about damage that I disagree with is that martial classes are required to rest just because casters want to rest.
