I plan for my first playthrough (I will be doing mutiple, likely simultaneously), to play with a group of friends I play dnd with, so my first character is likely going to be pretty flexible, to fill in around what they want to play. I have a preference for casters, especially gish casters, so Warlock/Paladin/Ranger are all pretty likely, but depending what is needed I could go for pretty much anything. (If it ends up a martial, I will probably prioritize subclasses w/ spells/spell-like abilities, EG Way of Shadow/Elements, Wild Magic, Eldritch Knight, Arcane Trickster, etc.)
