While I appreciate the hard work that likely went into this guide.
Honestly, truely, there are only a few useful crew skills a the moment. And this applies to all classes.
While your leveling, cybertech (+scavenging and underworld trading) will help you make armor and mods for your moddable armor for you and your companion. You can use your commendations to buy enhancements. The enhancements aren't optimal, but hey, its just for leveling.
You'll also get gifts from underworld trading to give to your companions.
At level 50, you use cybertech to make a set of epic armor and mods for you and your companion. You will do the daily +2 quest on Ilum to get epic enhancements for you and your companion.
Then you drop cybertech like a bad habit and pick up biochem (+bioanalysis and diplomacy).
You work up biochem and diplomacy until you can make a set of rakata stims. Yeah, the rakata stims got nerfed. So what. They are reusable and they work just fine.
Once you have your set of rakata stims, you drop bioanalysis and pick up slicing. You have to keep biochem in order to be able to use your rakata stims. You'll use slicing to get credits + slicing parts + schematics and missions you can sell. You will use diplomacy to get crew gifts and to increase your light (or dark) score to light V or dark V.
And that is how crew skills work in this game. Anything else you pick is basically, literally, of little value except for roleplay reasons or just because you feel its interesting. Patch 1.2 didn't do anything to change that.
You are not the first person to comment that certain crew skills are worthless, and you will not be the last. Yes, I'm well aware that some people think only biochem is useful, and that you should drop every other crew skill. Awesome, I am happy for you, but I disagree.
Being able to craft for alts is extremely useful, being able to make money from crew skills is also helpful. I have not once been able to make money from biochem, but constantly make money from artifice, an allegedly 'worthless' crew skill. I also constantly supply my characters with quality item modifications.
You're entitled to your opinion, but this really is not the place for it. There are countless threads on this forum about how unbalanced crew skills are, I really do not want nor need that kind of pessimism in this thread, with all due respect. Thank you for understanding.
PS: If you decide to continue this conversation here I will not respond to it. This is my full and complete reply to it, I have nothing else to say nor add. I'd very much like to keep this thread on topic if possible. The only reason I am posting this at all is because I keep getting messages like this on this thread, and I'd like them to stop appearing here.
