Taking a break from refining the three principles for a sec. Jason Miller, in his blog recently posted about short and long forms of rituals. Omnimancy, as a rule, does not have any rituals or tools. At all. That was part of the point of it.
"We want you to be able to do magic if you were blind folded, cuffed, ball gaged, and stuck in the trunk of a car."
I never, thankfully, have had to see if I could cast while stuffed in a trunk. But I never saw duration as a positive thing until that very post. In my head, the longer it took, the more inefficient it was, as things should only last as long as absolutely nessisary. That is a very worker bee mentality. The mindset of a production based, results driven person.
Time and Process as good things are much more in line with an Artist's mentality. The mindset of a process driven person.
Odd that I never thought of it that way before, as Liturgy is one of those things that I get nostalgic over from my Olde Catholic days.
As Jason said, long form is great for groups, especially when there is one celebrant and the rest "turn the wheel" and raise power. It's also very good for bonding a group togather, and forging a group consciousness in ritual space.
Long form rituals and especially ritual implements are great for teaching. The process of making them, is initiatory for the student, and if the group has a dedicated set just for group work, an tool used for fire, for every rite involving fire, by that group for years will teach students the knack of dealing with that energy, just by virtue of them handling it or useing it once in ritual space.
In that way the tool itself can become a teacher, kinda like training wheels. And if the tool in question is involved with a particular spirit in some way, that spirit can be a really real teacher, even if they are directly pumping intuitive flashes into your mindspace instead of going through all the trouble of manifesting physically in a fair and comely form, and teaching you in your native tounge.
See, spirits use short form too!
