I concur, ArmsTech is sooo underwhelming!
I can't even make a blue VibroBlade...150 attempts and not a single blue schematic. Is this broken or what?!
Also, I can't make any Orange items until lvl 48. Going out of the way to make a purple provides little to no benefit. I completely wasted my time getting to 400 when the weapons are worthless and the only additional thing I can make are barrels.
Would have been nice to have another item to make/sell, like ship guns or something. Clearly, one of the worst TradeSkills to choose!!!
