1. School of Enchantment Wizard.
2. The Shield spell, and a revamped reaction system. That way the Abjuration specialist can compete with the Evoker.
3. Paladin and it's 3 PHB subclasses.
4. Ritual Spells.
5. A good aligned Dwarven companion.
6. Hexblade Warlocks, Pact of the Blade, and Pact of the Tome.
7. Aasimar, Half-Orc, Gnome, and Dragonborn races added.
8. Wizard Schools of Necromancy, Divination, Illusion, and Conjuration added (the Transmutation specialist sucks).
9. War, Death, and Tempest Domains added to Cleric with the Spiritual Weapon spell.
10. Multiclassing.
You can scratch off Hexblade from that list. Larian has already stated that we will only see things from the PHB when it comes to the classes. So for Warlocks it's going to be Archfey, Fiend, and GoO Warlocks.
