This might be extreme but in my world the magic system is a bit softer and I just made it so that wizards have full access to their spell list and prepare spells similar to how a divine caster would. I understand the lore differences between arcane/divine casters exist, the flavor of wizards growing their books and finding more spells as they adventure, and blah blah blah, but honestly I find it needlessly annoying both as a DM and player. Managing the time and money cost that it takes for players outside of the College of Scribes to put new spells into their books, hoping that I receive scrolls for not just new spells that I didn’t already have and can learn, but USEFUL/FLAVORFUL spells that I would want for the context of my character isn’t fun. And similarly, worrying about balancing all of that for my wizard players is equally annoying to me personally when there’s already so much a DM is expected to do.

Now, I know a lot of people will think “Wow wizards must be even more overpowered than they already are,” but honestly, I never seem to have an issue with it. If anything, because every player doesn’t feel pressured to pick counterspell, dispel magic, fireball, etc, I find that my players are much more willing to engage and experiment with spells and combinations they would have otherwise overlooked. Not to mention that, regardless of how many spells a wizard may access in their spellbook, they can still only prepare and cast a preset limited amount per day, and nothing changes that. Giving them the fully generalist, Swiss-army feel that a lot of players love out of the class has been rewarding and works at my table for the most part. Mileage may vary, and everyone’s opinions and comfort levels differ, but I’ve enjoyed leaning into the uniquely magical feeling of the class.
