It become 1 during beta of 3.0. It was intentional for 3.0. Was it a bug or not I won't call, I asked support about this during beta and they explained that this change is coming.
My point was it has nothing to do with going over spawning tables. Let's say 3.0 starts with such table with version 3.0. So they will do overview and will have version 3.0.3 for table
Anyway, will be interesting to say how they will tweak spawn rates, because there's lot of things already good in 3.0.
I've played during the beta and i don't remember to get 1 data/material in any of my material hunting.
Before they release the fish enginnering im collecting stuff to enguinner the chieftain for tests, i have sure that in beta 3 all the drops are 3 for 1 (Like it is now on live)
