@Steampunkette The DC20 casting classes literally all use different mechanics, you're completely ignoring what's in the game by only listing the base number of cantrips and spells known and acting like that means each class is very similar just because those numbers are similar.
please explain to us simpleminded ones how there is a difference in mechanics of each class? In detail!
Spell list that certain classes have access? So same thing as D&D?
Mana points? So same thing as variant spell points from D&D?
From the playetest PDF it does not look like any class is different is spellcasting from another. Except what spells can you pick.
Joint spellcasting? that is the big thing?
Sure, it's a cool idea, but it will be used once in a blue moon.
Verbal, Somatic and Material components? So, again same as D&D.
Maybe if DC20 went full 3.5e psionic and casted "spells" without any component and only thing you need to worry is how the spell manifest in the world and how obvious those effect are, maybe there would be something.
unfortunately, nothing really new.
Sure there are few nice ideas that are primed for mining as house rules for 5E
