As you say, the presence of the spellbook is what distinguishes the two the most thematically. Mechanically in 5e there isn't much distinction between them.On the other hand, that one detail is huge. Did you see the other thread on the cost of training a wizard? An academic book-learned spellcaster is extremely specific as an archetype. The background for every wizard has to account for the costs and needs of training. That one detail limits wizards to privileged backgrounds (or requires plot contrivances like "I stole a spellbook"). There is very little room for spellcasters of lower classes or for spellcasters that didn't choose to be casters, or for spellcasters that inherited it from another creature.
You know what, I answered this with an eye to "Let's Streamline D&D" but now I'm gonna answer again (not changing my votes mind you, just as a thought exercise) with an eye to "Let's Change Things Up!"
So, Right out the gate; Cleric, Fighter, Rogue, and Wizard are OUT
Sorcerer is basically Wizard 2.0 so Sorcerer is also OUT.
Now this defaults us to 7 classes: Barbarian, Bard, Druid, Monk, Paladin, Ranger, & Warlock.
HOWEVER, Eberron will give us the Artificer in a month.
SO, we're gonna cut one more core class and have the Artificer. Because.
My cut target comes down to Barbarian, Monk, or Ranger. Since we already tossed the Fighter, I want to keep some pure combatants, and to me, that means losing the Ranger. Barbarian is pure Fight, Monk is Fight with mystical Fight buff. Ranger is fight but also nature magic, and a really messed up pet.
So now we have
Artificer - Our CORE Arcane caster now.
Barbarian - Our Primary Melee Combatant.
Bard - The all-rounder and skill monkey. 1 casting subclass, college of swords, new subclass that grants more skills, expertise (double Prof bonus), and Sneak Attack, new subclass that grants the Nature/Scouting part of being a ranger.
Druid - Our Primary Divine caster and Healer.
Monk - More Melee.
Paladin - Just here to annoy people. (joke) Support class, extra melee damage and off tanking, support healing and buffs.Spam Decursive.(Joke)
Warlock - Blaster Caster.
Also, no races from the PHB.
Now let's play!
It would be too interesting for my tastes. Also, well, I am not keen on the concept of the Artificer, I don't like Bards, and Warlocks are lack luster IMO most of the time. Besides, I don't like a lot of the races outside of the PHB with only a couple exceptions.You know what, I answered this with an eye to "Let's Streamline D&D" but now I'm gonna answer again (not changing my votes mind you, just as a thought exercise) with an eye to "Let's Change Things Up!"
