i completely agree, i feel like the Potion of Immortality should stop you from aging altogether, because that's what immortality has been with the sims since forever. aging to an elder makes you easy to die just from doing any fitness/active interaction. They should definitely make it so you stop aging the moment you drink it, like how vampires work. Or atleast add another potions (which is highly unlikely) to age freeze and get rid of one of the romantic potions because both of them do the same thing.
It is probably done like this to fit into the lore that witches are mostly described as elderly.in fairytales.
There is reason why it's called spellcaster, not witch and not all witch that old in story, some are young and beautiful in story lore, and some old ugly witch willing to do dark magic to make them young beautiful. hmmm how about mage skeletal rather than elder, a lich!
It is called a spellcaster because they didn't want to limit it to only Witch, Warlock, Alchemist aso. These are by the way also predominantly described as old.
