Damage dealt and magic item effects can break the argument of multi attack vs single scroll. It really depends on the situation including what you are fighting. Action surge is a moot point since it is limited. Yes partial classes have limited spells. It makes scrolls more valuable to them. So?
I never said anything about learning spells from scrolls either. Just using them. Like I said before, how frequent you get scrolls is more the issue. So if thats all then that as they say is that. Half decent wizards dominate games so don't expect me to have sympathy for the class. Especially when this is a buff to a team encounter and a indirect massive buff to spell caster spell slots and upcast.
All I can tell you is agree to disagree.
