Side note : giving resurrect spells via scrolls is also a bad design to me. D&D5 introduced the downed state precisely to avoid being either dead or alive. It brings so much tension just when one of your players gets down, like every other player stops what he's been planning to do and just tries to figure out how to help or heal him/her. Giving away Revivify spells to all your group members takes away this tension and makes the death part of the combat just as in DOS:2. D&D5 isn't like that at all. Death should have consequences in the Forgotten Realms.
I agree that player death is handled better in the table top rules then currently in the game. But from my perspective, it is much easier and quicker to roll up a new character at the level that you died on and be re-introduced in the story in the table top version then that it is in a videogame. Plus you are locked out so much content and maybe even the whole game if half the party dies in a video game. The DM in a table top can just roll with the dice and adapt when necessary. A video game is much more difficult to achieve the same result.
As for the OP, Classes should stick to their respective spells for their class and not be able to cast every single spell available to them. We have classes that can do in the game. Looking at you Bards. But the rest should stick with the magic provided by their patron. Warlock magic is different then that of a paladin.
