So you are saying that 100% every spell in the wizard arsenal is available by level up and there isn't a single spell that is only learnable through scrolls except for Shovel? My main mindset of this is you actually using the ability to build your spell collection as you level or you trying to respec your character at level 12 to wizard and trying to learn the spells you missed since you didn't level with them. With the ability to actually learn spells at random with an ability or a vendor that sells all the old stuff, that at least gives you a way to fill out the missing stuff or what you are looking for for later.
And if you already have access to EVERY spell in the wizard arsenal just from leveling up, what's the purpose of the scribing ability? Is it largely just useless "Flavor" for the class that isn't really an advantage beyond saving time at Withers when you want to change your spell loadout while still remaining a wizard or the spec you currently are?
As for the forms and their stats, I can understand it from a tabletop perspective, but from a gameplay perspective, it doesn't really translate over that great. Don't get me wrong, have a druid with maxed Wisdom, Intellect and Charisma because Strength, Dexterity, and Constitution are completely worthless to me makes for a pretty good party face but the fact that those other stats are completely useless for 1 of the 3 subclasses seems off. The Spore actually care at least about Constitution and Dex and they aren't even the melee oriented subclass. Even wizards and sorcerers care about those stats some as casters.
Guess I can give it to you on the idols part.
My big thing I am getting is, I can understand some of these things likely translate over very well to the table top, not so much to the videogame section of it.
