So I finally ran out of ingots (never in my life thought that would happen!)
Anyway set up another miner in addition to my guy that normally mines.
Went to get an upgrade book so I can mine normal gems and had a terrible thought.
Right now with no upgrade my guy mines lots of crystal Blackrock, Fire, Blue, Perfect's etc
if I upgrade will I get less of these while getting the common ones!
Anybody ever test this (like you perhaps Cerveza)?
