Nothing too big that's out of the realm of possibilities and even stuff we already know they will probably add at one point but you are eager to play around with
Here is my list: Feats: War Caster, Resilient Subclasses: Tempest Cleric Spells: Spiritual Weapon, Booming Blade Subraces: Githzerai (Or any other +2 wisdom race/subrace [I really want firbolg but I know it's not gonna happend])
