Split the Tech Part Pool up into 2 (excluding MC5). 1st pool = the parts from NC1 that would drop from traditional tech dropping mobs. 2nd pool = NC2 parts that would drop from high lvl DoY Mobs.
Also create more dungeon/mob specific items. I miss trying to find a filter heart 2 out of a terror raptor, and it is so fun as a first timer trying to go thru el farid lvl 2 then getting the armor when you finally complete it.
