"What were they thinking?" is a very good question and one I keep asking myself. I can tell you from a perspective of a 400: armormech, scavenger, and underworld trader I will not be spending one single credit more on my crewskills. period. Until I know what it is they are planning on doing about the major issues here.
1) Issue one is the obvious benefit to Biotech that you just can't compete with in the other trade skills. To have basically a perma buff to your stats, a 3 minute adrenal that basically equals another cooldown, and a medpack you never have to spend money on is insane. Having something close to these in the form of a trade-able consumable is only balanced if they were FAR FAR more affordable. The bottom line is that someone could spend ~100k of these consumables in a 20 minute WZ. To have these stats and abilities permanently available to Biochemists just blows away the handful of stats you would get from say the Armormech Rataka gear even IF you crit when making it.
2) Issue two: now you could argue what about all the other cool stuff you can make with Armormech?? Well after RE-ing roughly 80 high level crafted greens and a few blues I got nothing to show for it. Never mind the fact that even if I DID get a schematic who's to say it would be one that was useful to me or even useful in general (OR you could get the same one more than once). While other screwskills (Cybertech, Biochem) get a linear progression for their RE's - in other words its just a matter of getting that blue schematic then the purple schematic just once.
Now there are other issues that I am sure people would list but these are the 2 that really stand out to me and I can not believe that anyone designing these systems thought this made sense. Is it just unfinished? Did they really plan this out? Makes me really wonder "What WERE they thinking"... and can they think about it some more 'cause it is not done. As I mentioned, I will not be spending anymore time on this until I find out what the plans are.
One last note that really makes me a bit sad - this could hurt subscriptions. Here I was last night trying to figure out what to do at 50 - here was my experience: Logged on at Ilum and did a couple of the dailies - got bored and flew over to PVP area and was promptly invited into a 12 or so person operation. Drove around for 10 minutes or so looking for pubs to engage - only 2 we found were right outside their base. I jet charge to one and instantly die - guess that's too close to the base now... Drove around for 10 more minutes and did not see a pub soul - most of my operation either disco-ed or left. I joined the WZ queue. Did a Hut-ball. Drove around a bit more on Ilum 'til I heard someone asking for a tank for HM Flashpoint. I start talking to her letting her know I am probably not geared well enough - she thinks I will be ok but they are still looking for a DPS. I joint a Voidstar - mid way through the flashpoint person lets me know its a bust cause they just can't find another DPS (What?). Half way through the WZ I lock up jet charging to someone (never have I once every had a lockup or crash in this game before 1.1) Done. bored. did not bother logging back on.
My point to all this? Crewskills could be a great distraction - something to work on in between all of this stuff - something to strive for but the only thing that makes sense is to reroll Biochem. More experiences like last night will definitely = cancelation.
