Yeah, I gotta say I too enjoy the ability to Cast an action spell and a bonus action spell in the same round and not be limited to choosing to either Casting a cantrip then bonus action healing word or shield of faith OR choosing Cure wounds and wasting my bonus action doing nothing because clerics have exactly 0 cantrips that are bonus actions. The ONLY thing that clerics have at early level that allows them to have a full action and bonus action every turn Larian hasn't added yet and that is spiritual weapon. because then at least you can enter battle round one you shouldn't need to heal at all so yo can Example: Action> Sacred Flame, Bonus Action> Spiritual Weapon from there as the fight progresses whether you Heal or Bless or w/e you can always use your spiritual weapon to bonus action attack the enemy.

So, I guess what I am getting at is this. In BG3 I am fine with the fact that they have removed the one spell/ one cantrip limitation to spell casting, BUT if Larian wants to give Clerics back their spiritual weapon I'd be fine with the classic 5e rules.

That said... in later levels (whether Larian decides to keep it the way they have it or to implement the 5e RAW on this matter) the big bosses tend to be kinda bullshit with action economy anyway, because not only do they have whatever "normal" abilities their cast of creature/ class of character would have they also get legendary abilities. (though I suppose depending on how much you use your tadpole, you and your companions might end up with some pretty bullshit abilities too)
