wands were in PHB as options to be crafted, same as potions and scrolls.
and you could buy them normally,
didn't take a genius that can sum up 50 scrolls and/or 50 potions are much more than 1 wand.
granted, we were also stupid and in our 1st campaign didn't buy wands...gotta learn the hard way.
Also in FR setting book, wand with 20 charges was option for starting gear.
How many people played FR and chose starting gear from it?
How many people really grinned the magic item creation rules? Without prompting I saw F all of it and our group was plugged in.
I also have 50 odd 3E books. Most of them barely got used tbh. Even the big 4 complete books and we played a lot.
Think you're vastly over estimating the people who did. Vast majority of players any edition I suspect are casuals. PHB only or close enough to it.
5E maybe Xanathars and Tashas but that's because they only really did 2 player books.
Even then if it's not a cantrip or absorb elements how often do you see a spell from the books used relative to phb?
Vitriol spheres been in the game since 1996. Ever seen it cast? Ice knife outside BG3? That turned up 1990 iirc.
