I agree Armstech is horribly bad, but lets face it most professions are. Only two are in my opinion worth spending time on, and thats Biotech and armormech. Armormech can craft some seriously nice rakata gear (only belts/bracers, but equal to tier 3, and better if you crit it and get an augment), and biotech for obvious reasons (never-ending healingpots and never-ending stims/adrenals).
I'm seriously considering dropping armsmech, even though I do earn a bit on GTN atm (when people have kitted out their companions, no one will buy supbar gear any more).
Look up the schematics for armstech on torhead or any other datamining DB - there is NO raid drop schematics. AND the crap recipies we can buy from the trainer (Guardmaster for instance) requires 3 biometric crystal alloy to make! And its freakin worse than a tier 1 weapon!!! Oh I got worked up...
Biochem use one biometric crystal alloy to make an non consume on use medpack/stim/adrenal...Armormech uses one biometric crystal alloy for their Epic rakata recipies. But Armstech has to use 3 on something that a tier 1 weapon will replace.
