With the additional info provided, I can really see it.That can be true for you and it can be false for me. I know myself.
As I mentioned in my post above, I love the idea - it just doesn't work well for me in reality. For those it works for - it is great. For me it is a burden.
Sounds great but can get messy really fast.
Party fighting 6 opponents and the wizard cast a mass hold person. You have to determine, not only each opponent made/failed the save but to what degree. Suddenly you are tracking multiple conditions from the casting of one spell.
That can add up fast - that's kind of a bigger version of what burned me out on 3e.
So great mechanic, but probably not for me.
