I just opened a help ticket about this issue. It was my understanding that we we going to be able to dress companions how ever we wanted. It is bad enough that the message about not having access to old companions was so vague I lost some great looking items not to mention the 192 bound to companion gear awarded from Sor flashpoint on yavin that was turned into bound to legacy gear in 4.0 update. Then I was sent all the ol gear from companions that I removed and got rid of long ago. I thought the whole idea of this "GREAT COMPANION CHANGE" was to have the ability to dress them up and make them look how we wanted.
It is kind of stupid to see everyone with the same looking Lana Beniko, Thank goodness I have some HK-51 Customizations so I can at least be somewhat different.
