Did the Zodiac signs ever do anything beyond create preset traits or affect compatibility? As someone who doesn't actually believe that stuff, I'd rather see traits and maybe added interests and tastes used for compatibility than some stories told about stars. But really, I'd prefer if it's just a bit noncontrollable by me - this is one area for a bit of "magic" in... sometimes opposites are compatible, sometimes similarities help, but sometimes it's just "chemistry" or none.
