Thank you Deriven Firelion, this is exactly what I was looking for. I'm attempting to get my group to try pathfinder 2e. We play a lot of games but usually fall back to d&d 5e. And due to the asinine spell prep rules pathfinder was going be the first game my group has ever said no to playing. But if I bring these house rules I might get them to give it a try.
See, in 5e, the Wizard is the only caster worth a damn, because WOTC thought they knew better than the classic Vancian Casting that's always worked well. And you wind up Sorcs that are garbagio, Warlocks who're OP as f#%!, and Wizards that are just plain the best casters in the game.
Why would you want to subject your table to that clusterfudge of imbalance? For the first time in forever, casters are balanced.
Sorry but this is an obvious opinion of someone who hasn't played much 5e. Hell the divine soul is one of the best healers in the game. their metamagic twinned spell allows them to be the only class to have 2 of the most powerful concentration spells going at the same time. Don't get me started on the storm sorcerer. and just giving a sorcerer 6 levels of paladin makes it hands down the most powerful thing in the game. The trick was to specialize a sorcerer can cast any spell more effectively and more creatively then the wizard. the wizard can cast more spells total.
