I can't find it anymore but Sounssy has a comprehensive post on Arcanima.
*summons Primal Sounssy*
Basically, Arcanima is VERY VERY precise. The likelihood of stumbling upon a viable spell by chance is slim to none. The process of invention is likely many years of trial an error. Adjust this angle, shorten this line, close this circle but leave this one open. Fine tuning until it's perfect. Most spells used today were developed centuries ago or are based on Allagan and Nymean magical sciences.
I would say the thinking power required for creating new and well-functioning arcanima is the equivalent of the thinking power of the mathematicians who came up with modern algebra and sit around all day figuring out the world's unsolved equations.
