This makes me laugh, I just can't help it. Of course they are semi-costly, they USED to be an "epic" drop, now they are given to everyone holding 25 BH comms and people started pumping them out left and right for friends, credits, raid groups etc.. This is the trend of releasing things to people for comms or whatever currency rather than putting it out there for people to actually "achieve". This is just my point of view but the day they released the stims to everyone their value went down and their demand went up because they are available constantly and now people can't keep up with making them....
Back before the server merge, for the longest time, I was the only Biochemist with Exotech Aim and Exotech Cunning stims, and made MILLIONS selling them on the GTN.
Now that everyone can get them and can easily purchase the recipe, they are QQing about the cost of mats.
They are the BEST IN THE GAME... of course they should be costly to make people... get over it!
