I no longer play Star Wars The Old Republic, but I will still update this thread when there are changes that effect this guide, and I am allowed to post on the forums to do so.
I don't see any changes in 1.3 worthy of mentioning besides, perhaps, general changes to the value of crafting criticals (which I still feel are better than efficiency) and augment slots. As far as I can see, HK was not added this patch.
Please continue to enjoy your Star Wars adventures.
