Ok, this may be rather long so appologize in advance. It would appear that there were multiple people working on the Cybertech recipies with no clear vision of the big picture. Either that or there are a lot of recipes that were just never made available to the players.
Here is a screenshot of my current learned recipes and the ones on the trainer at level 400. I am currently a 400 Cybertech and did not buy and of these recipes as they are useless to me. I am using all quest rewards in my current tanking gear.
Screenshot of all the level 49 recipes. As you can see these are all useless to a tank.
Screenshot of the Tanking mods I am currently using. These all came either from FP drops, PVP gear or as quest rewards. I decided to go with Cybertech as I thought it would give me more flexability in what I wear and how I stat that gear out. Not being able to make below mods is really putting a dampner on my plans...
Up until level 31 I was purchasing the below mods off the commendation vendors. After 31 all of the recipes for Cybertech Mods changed and the Guardian mod was no longer offered on the commendation vendors.
Here is a screenshot of the level 38 vs 43 tanking earrings. Notice the name changes yet again and the stats drop. I actually prefer the level 38 earring over the 43 one as it gives 21 more DEF.
Finally this is a screenshot of the level 43 crafted earring vs the PvP level 40 earring you can buy with PvP tokens. The PvP earring has more DEF and END than the blue crafted one.
Below screenshot is one of the reasons I took up Cybertech as my chosen profession. It was supposed to give me the flexability to help make my character be able to wear any heavy armor that I wanted. How many Jedi Guardians do you see running around in trooper armor?
What really happened though is as I bought this armor I realized that I had to strip old armor and PVP Orange armor to outfit trooper armor with the correct mods for tanking. Because I couldn't make any of the tanking mods that NPCs give out for quest rewards and that drop in gear.
In closing something is seriously borked with this profession. I can buy blue Guardian armor plates off the commendation vendor all the way through my leveling career. So, why would I ever buy one from a Cybertech? The recipe name changes throughout the leveling of this profession make it very confusing to the player to understand the DEVs plan if there is one for this profession.
Many of us chose this profession as we wanted to be able to customize Orange gear and be able to wear what we wanted. As it stands now I can make blue armor plates that I can buy off a commendation vendor and that's it for my tanking gear. I am still reliant on buying PVP gear and stripping the mods or getting FP drops and stripping Guardian armor to place the mods into my Orange set.
Someone needs to take a serious look at this profession and overhaul the recipes or give us the B version schematics so that we can make all of the mods we are supposed to be able to make.
