Increase the drop rate for blue prints. Ever since they came out it's been driving everyone nuts on the sketchy drop rate. The very first day it seems everyone got one, then got one from frosty... but ever since that basically nothing, few people received 1 more since that time in my guild. This appears to be a "diamonds only" feature since the only people that have great buildings are those who bought them. I do understand of course diamond buyers will get them faster, but not months faster. I read somewhere on the forums that you may even get duplicate blue prints... I hope that only happens AFTER you've collected all the prints for a building, because at the current rate they are dropping plus dupes, I'll be able to make one months after the game is over, making little use for them.
