I think they also asked in the survey if Players are happy/content with the Medal/Stamina Ratio. I would like to add to this that luckily Japanese Gaming Companies are still concerned with their public image and their Reputation (unlike most Western Gaming Companies). So since it's a Japanese Company handled by Japanese Devs who are often times very polite and open for feedback i think we will see a fix for this as well. Maybe i just only farm all Ampules from 700 till 1200 currency now and save the rest Medals till the rates are better.
