currently each trait line of three major traits (adept, master, and gm) is spread into three specializations. to increase diversity and choice, have it where two or three trait lines could be placed into one specialization so you could potentially use all the traits of a specialization at once and highly specialize in the specialization (with either minor traits increased per specialization or just loss of minor traits by combining trait line selection).
on that note with something related, if each specialization gave an extra skill to use (in addition to skill bar and profession skills) for a trait line used in it, each specialization could have three skills that could possibly be gained by putting three lines into that specialization (just something that came up with it).
these extra specialization skills could be specialization mechanics of their own.
