So, given a very high Lore character (Superb, plus several points of Complexity focus bonus), and given that maneuvers can create free taggable aspects (like "There's a suitable circle here", "the enemy is distracted"), and given that we don't have any kind of time-to-exchange conversion: Where do you say "No, you cannot cast now, it's too fast?" I can't just say "not in conflict", because as my player has pointed out, the Lincoln-Douglas debates (social conflict) would have provided *plenty* of time to cast moderately complex spells, let alone really simple ones. And there *is* no "this is a social conflict so it's slow, while this here is a physical conflict so it's fast" division in the Dresden Files.
I can stat up a Thaumaturgist who can toss off complexity four rituals trivially (so, a sticky maneuver a round) and who is likely to take no stress from it most of the time; she'll need to take a minor consequence very occaisionally, when her control role fails. Then again.... maneuvers are maneuvers, any skill should let you do them. The thaumaturgist *can't* be the attack monster the Evocator is, because Evocation's discipline roll counts as the attack roll while the spell strength counts for the weapon; it's effectively twice as powerful as the thaumaturgist's attack. The Thaumaturgist can do much more complex rituals (9-15) in combat time with a bunch of free tags from maneuvers, but then the magician or the party is spending a non-trivial number of in-conflict exchanges setting up for the spell (whether officially spell prep, or used for control and/or paying off for things like transformation effects); but that actually seems pretty cool, and encourages the wizard to enlist the group's cooperation instead of stealing the show solo. (Running around sticking candles in appropriate places while yelling for the party to keep the enemies off of your back while you concentrate seems to fit nicely into this universe.)
So... is there really a problem that results from taking the "you can start casting as soon as you have enough lore + taggable aspects to finish spell prep" literally, and handwaving the exact time?
