Ogre Mage
Hero
For classes: Sorcerer, Warlock, Bard.
Innate sorcery and the larger number of spells known are a game-changer for sorcerers. So are the better metamagics. The changes to warlock invocations are also exciting, although I wish the class got its 3rd spell slot earlier. Bardic inspiration is better and we get expertise earlier.
For subclasses: draconic sorcerer, valor bard, trickery cleric, light cleric (was already good), archfey warlock, great old one warlock, circle of the stars druid (was already good).
