Right. Given proper parameters, it would be feasible (and possibly quite cool) to play a caster that routinely casts spontaneously. But given that the results are left to the other players (some who might even be directly/indirectly involved in the same scene), and given that the majority of us are inclined to get a hearty guffaw out of the comical misadventures of others (hello, OT?), I'm inclined to avoid it for the most part.
So far, I'm treating it like the "ooh, let's see what this button does" feature but wouldn't rely on it for anything important.
I plan to do just this, my character is intentially restricted to not having any spells. However the skill distribution I picked means spontaneous is a bit of a gamble right now, guess Rituals will be his thing until he has more experiance
