A biochemist gets an extra item when crafting stims, adrenals, medpacks
1 extra item for crafting three. Relatively tiny sample size and small return mean crit crafting is barely worth mentioning for biochemists. It's really quite sucky when you look at the cash cow cybertech where a crit can net you a few hundred thousand credits.
That said the OP suggestion is idiotic. Random crit crafting gear being BiS is the whole reason they axed the old augment system and added kits in the first place.
I wonder would there really be any harm in removing augment crits entirely and just giving 2 items for a crit across the boards.
