A sorcadin can be played as a control caster. You can cast some control spells (with some metamagic to make them a little better than usual) and then use booming blade/green flame blade and opportunity attacks for at will damage and smites for nova. Even just Paladin 2 gets you smites, lay on hands, armor and some HP and if you go up to Paladin 6 you get the aura to make saves great. Take divine soul to get some cherry picked cleric spells like spirit guardians or go with one of the new sorcerer subclasses for the extra spells (and some handy effects like negating magic resistance or having always on subtle spell).
