I’m guessing the entire reason for all of this is simply the following.

PLD -> Purely party based job. S-E attempting to force the player to actually rely on his party members. Besides…we still got potions. I use them in emergencies when I see that the healer is either busy/ too far / or not paying attention. (Which happened once at the final boss fight in copperbell mines)
GLD -> Everything else(mostly solo play)

PS: Completely unrelated but this topic should be in the "Classes & Jobs" section of the forum. Just saying.
