what is final mechia boss battle success rate supposed to be now? I thought it was 5 wins you gain a level, 5 losses you lose a level, with 210 max. It seems to be 5 wins you go up, 12+ losses you go down from my recent experience...
I have been steadily losing there, trying to get the last 2 girls, ever since they corrected the double equipment bonus. I have dropped 5 levels since the correction, despite losing most of my battles (my last run, in 20 attempts, i won 4 times, lost 16 times, and ended up at the exact same level - I gained 1 with one of the wins, and lost it back with one of the losses)
