User blog comment:KodachiZero/Version 2.8.0 Changelog/@comment-28010705-20160923100417

This update is very confusing for me. I don't know if you noticed the same thing but drop rate is now very low:

Casino (high/low): The chance of reaching the 10 wins in a row in very low (from my own experience, sure). Probabilities seem to be reversed. Moreover, each try now costs 1000 coins (instead of 100 previously)...

Expedition rewards: I never dropped prisma coins since the update. Less chance to pull 4* or 5* weapons, a lot of gold pulls; surely for casino coins resupply...

Poor free users :'(
