If you have the money to buy the HK perk to unlock him on a lowbie, then chances are pretty good you have the money to re-gear him appropriately.
Some people might have spent their legacy coins on this you know, like i did.
Made a thread about it last night.
No proper customer support reply so far, also made a ticket with no luck.
Lets hope this is a bug that gets fixed quickly because he is completely useless if you don't have droid gear for your lvl...
