The design, sizes, and depths involved will influence how well they perform without dividers. The original omnifussors (with the recognizable QRD pattern) need the wells more than the newer skylines, and the newer ones like divider-less skylines, and also hemis and Berger's designs with dividers, diffuse more uniformly, especially in arrays of multiple units. So technically, the well-dividers are a required part of technology, but practically, for some combinations of element sizes and design, you really don't need them.

thanks a lot everyone
