I agree with the use of a queue system in the bookbinder, but do not agree with anything else. It will take a long time to get each individual geologist up the tree or part way. I do not think that at this moment anything needs changing except putting a queue system in place, even if you upped the gold required for the manuscript from 10 for 1st level, 20 for 2nd level, etc. Or put in place some challenge to get an extra queue slot, either by purchase through gems or through guild coins. Just an idea.
