I was disappointed with the legacy gear in SWTOR. After a few levels after level 9-14 the stats are no longer impressive and it doesn't level up.
I think the way to give an alt the advantage in SWTOR is to have your main purchase weapon/armor modifications from the planet commendation vendor as the alt levels up. Sure there is a fat chunk of credits that can be passed on, but most server economies are not that strong to provide every needed modification at all level ranges. I'm on The Swiftsure and I have a hard time finding modifications at the exact appropriate level on the GTN. I doubt The Fatman would be much different.
