I really think that scrolls should be locked into the classes who can cast it like 5e and that if you cast a spell above a level you are able there is the % chance of it failing. Being able to have tons of revivify scrolls or having fighters / rogues / monks etc buffing themselves with scrolls kinda breaks the point of casters.
Just my 2 cents.
I think they should be locked to. If you want to get a character up you should just use a potion, known spell or healers kit to stabilize them at 0. If you die, you should be forced to reset the combat if you want to save them (unless u find a cleric in the world like BG1/2 with raise dead). Otherwise death becomes less and less off an issue if every party member can raise the dead after or in every combat
