I'm really not sure if this goes here, or in advice. But I do need some help considering whether or not to impliment this variant rule introduced in Unearthed Arcana.
More or less, what it sumns up to, is hey. You don't have a limited number of spells per day. Any spellcaster has a certain number of rounds they have to wait before casting any spell again, but no upward limit. The balance between spontaneous and prepared casters is that spontaneous ones have a lot less to wait before re-casting. And the wait time is calculated based on how high the spell you cast is, compared to the highest level spell that you CAN cast at that level.
Basically, almost half of our party wants it, and the others are neutral. But I really need to know what this does for balance. It theoretically makes a spellcaster immensely more powerful, but much less of a rapid-fire beast. I can't decide if this is a good thing, or a bad thing. Obviously, this will change PC and spellcaster tactics to try to draw things out longer, allowing them to cast more.
I personally like the idea, as it circumvents the "I cast a spelllll, FIREBALL. Wait, what was that thingie I just did?" Issue, but I need to know if there are any big unbalancing factors I need to know about.
