Thanks BrianO. I figured out what the problem was: it was Custom Function 5. Once I disabled that, it worked, firing full blast on both tubes.
C.Fn. 5 has to do with how the MR-14EX controls slave flashes in wireless mode. 0 will control Group C only, 1 will control Groups A, B, and C. If you didn't have any slaves communicating with the MR-14EX "Master" it wouldn't fire a full sequence; similar to the ETTL-failure I mentioned above, but for a different reason.
I don't think you had a "problem"; I think everything was working as it should. Did you try it on the camera yet, taking any actual photos?
