@Rhobar121 what you you mean by a double roll? You mean to use the scroll and then any roll associated with the spell?
I'm fine with that. There are a lot of good spells that don't have an important roll: mirror image, blur, healing word, darkness, bless, jump, magic missile, protection from Evil and Good, Shield, Shield of Faith, Sleep, Heat Metal, misty step, invisibility, spider climb, counterspell, haste, dimension door, greater invisibility. These are just the ones I judged most important from levels 1-4. Also, all the leveled surface spells might have surface effects that do guaranteed damage to enemies, making any attack roll/ST less important.
If you wanted to cast scrolls without making a check, you should have taken a level in a casting class.
I like that the scrolls use the caster's ability score.
