I worry about the delay with coming out with the circuitry formation. These other formation master's aren't dumb it's entirely possible that Rean making this kind of formation would be enough of a hint for his rivals to come out with a very rudimentary form of a circuitry formation themselves. Stealing his points, before he has a chance to present the idea. I'm not too concerned since this is a novel. but if this were an actual world; he might be taking a huge risk. Never underestimate the ingenuity of others. The idea for the light bulb has already been taken.
