Right now, a monk or ranger with improved defensive capabilities that allow it to stay in melee and work as a defender/tank is what I'd like to see.
I mean... Warlock with their 2/short rest (roughly 1/encounter) leveled spells that they don't have to prepare, Eldritch Blast, and Evocations and spells to enhance it... Not to say that more newbie-friendly magic classes or subclasses wouldn't be desirable, but it seems like what you're asking for already exists.I'd like to see a simple magic-user class, for people who want the fantasy feel of a wizard/etc but kinda get analysis paralysis when looking at lists of spells. Yeah I know sorcerer and warlock are pick-your-spells-once, but there's still that once. Maybe something with the mechanics similar to a Battle Master Fighter, spending limited resource points on extra magical effects based around a spammable cantrip.
