Wizard vs. Cleric Spells known and change in feel
A cleric can prepare any spell matching their level while a wizard knows only a few spells from which to choose. Every level the Wizard gets to learn 1 new spell and prepare and additional level of spell while the cleric can just prepare more.
Therefore the wizard feels like they get more at a level up,
It also makes playing a wizard easier since they have a more limited amount of spells, therefore lowering decision paralysis when preparing new spells.
What do you think of this theory?
