I appreciate this post greatly, thanks for putting this together, I know this will save me a ton of time as I'm already gearing battlemaster.
Right now I'm in 2 piece battlemaster, Helmet/Chest with the Weapon/Ear/Implants as well. Considering my guild is 4/5 EV hard and 3/5 Karraga Hard, I'm looking to replace certain pieces with Rakata.
The 4 piece of battlemaster Eliminator is a must for assault vanguard, so I intend on buying Rakata gloves for one piece. For the other two I was considering belt and an implant, or two implants, whatever is easier.

That's a great spreadsheet that was linked to me with all the location for Rakata drops, but it doesn't include the implants. Do you have any idea where they drop? I'm thinking nightmare patterns from bosses, but I'm not certain.
