Am i missing some other balancing factor, or are the save DCs for incarnum soulmeld effects *really* low? The formula is 10 + ability mod + "essentia invested in the soulmeld"--and that maxes out at 4 at 20th level, and is roughly 1/5th of level, rounded up, at each level. Spell (and most other class ability) saves seem to very consistently scale at a rate equal to half character (or class) level; why are soulmeld save DCs so low?
