I am happy to see ppl thinking of creative ways to make classes more unique yet maintain cohesion! I like the gla idea turning into drk/pld I would also parry that to the mrd as well, giving both of those classes the ability to pick between drk/pld. The mrd would be an aoe pld focus while the gla would make a one on one pld. And for the magic class give conj and thm the ability to become summoners/brd-like magic caster!!
