Well curiosity killed that cat...
I've had 1 facility running for a while and I can't say i've seen the QL mean anything or reported properly in the warehouse...
BUT
that isn't the major problem... I spent the 5 mil to upgrade the facility, of which it doesn't seem to give any better research in speed or QL but it also DOUBLED the monthly cost of the facility.
let me know whats going on here...
