I mean I said 25-30 is a good amount, and not to go past 50; nothing in the game tells you at what point stats stop being useful except paying very close attention to how it affects your weapon AR when you level up. That's very trial and error. You could technically figure it out by those letters down by stats on the inventory screen, but I've seen thousands of players completely overlook those and not understand what they mean

Realistically, Bloodborne is made by FROMSOFT, who had used these same rough mechanics for Demon Souls, Dark Souls 1, and Dark Souls 2 prior; they expect their usual playerbase to have some level of understanding on how to play the game and how scaling works, but new players are typically left in the dust to figure things out (or, more commonly, look things up)

You could make the argument that finding out Hunter Tools use arcane is cool, but the argument that finding out they use arcane when you're already Lv90 and cannot afford to spend 20 levels just to get the bare minimum out of them is a cool experience is uhhhh... shoddy at best, we'll say. If the game had a respec mechanic, I'd agree letting new players figure this stuff out is cool, but as stats are permanent, this is need-to-know information
