Biochem is still the ONLY crewskill that offers a steady dps boost in raids, as well as the bonus of increased survivabilty. I am currently 400/400 armstech and i am severely disappointed with the max level schematics i have available to me. The epic barrels are worse than the barrels available from ilum/belsavis dailies, and are harder to obtain than the barrels from daily quests. Biochem has superior stims/adrenals that are reusable (which saves a chunk of money for raiders) as well as reusable med-pacs which are incredibly useful during aoe phases of raid fights. My guild is STILL encouraging our raiders to switch to biochem, not because it has amazing bonuses (all of the crafted items can be purchased from GTN) but because NONE of the other crewskills offer ANY bonuses for raiders whatsoever. Crewskills need to have bonuses outside of crafted gear and mods.
