I may be jumping the gun because we are 6+ months away from even play testing the technomancer but I want to make a suggestion for it before the playtest drops. That suggestion being: The technomancer should be our first default flexible caster. In 1e every caster was spontaneous, technomancer included, however I feel as though perhaps the technomancer should have some kind of digital library of spells and be able to swap which ones are pre-programmed for the day. Actual factual prepared does feel too archaic for starfinder, so this is my proposal as I think it would fit the flavor of the class
I wouldn't bother flexible becoming the norm for all casters in Starfinder tbh.
I don't see it happening though.
