You should mix some crit with this build. I use the 50% more crit rating node on the skill tree and i am critting for 12k with a beam rifle at the moment.
Pretty sure the majority is random but some weapons and stuff only drop from specific bosses. rn tho the game is too underground to find a lot of guides, item tables, drop % etc
